98.210.197.51: /* Custom Events */

== Interface Based Design ==
Using a common <b>interface</b>, different Event registries handle different types of event registration:
# Event handler properties. Browser agnostic.
# Dom Event callback registration methods, considering delegation, IE event model, browser anomalies.

'''Source:''' https://github.com/GarrettS/EventPublisher

The implementation can be swapped out as needed for any given scenario or context, without having to try to accommodate every conceivable situation in one monolithic class.

==== DOM Events ====
DOM events need an adapter for addressing the great difference in old IE's event model, with <code>attachEvent</code>, getting a event properties such as <code>target</code>, and, <code>relatedTarget</code>, and addressing delegate listeners (See: [http://www.w3.org/TR/DOM-Level-3-Events/#event-flow DOM Event Flow]).

==== Custom Events ====
Custom Events are user defined so do not need any adapter. Custom do not need "on" conditionally prefixed to the event name, however DOM Event handler properties do, e.g.
<source lang="javascript">
EventPublisher.get(document, "onclick");
</source>

The custom registry does not try to normalize the event, either. The client can, however, access the adapter methods <code>getTarget</code> and <code>getRelatedTarget</code> from <code>DomEventPublisher</code>.

===Encapsulate the Parts that Vary===
Event handler properties are useful for custom events and DOM events.

For DOM compatibility, it is often necessary to have methods that will handle old IE event model or work with delegate listeners (See: [http://www.w3.org/TR/DOM-Level-3-Events/#event-flow DOM Event Flow]).

=== Common Interface ===
Each interface shares the following methods:
<source lang="javascript">
// Static:
get(src, sEvent); // Gets an event publisher.
addCallback(src, sEvent, callback);
removeCallback(o, type, cb); // useCapture for DOM.

// Instance:
eventPublisher.addCallback(sEvent, callback);
eventPublisher.removeCallback(sEvent, callback);
</source>

The DOM events interface has an additional parameter, `useCapture` for the capturing phase of the Event phase in <code>removeCallback</code>, used internally.

==== Event Handler Properties ====
Each event is a property name. The value is a function or null. The pattern works equally well for custom events on user-defined objects and DOM events.

DOM Elements
<source lang="javascript">
el["onclick"] = function(ev) {
alert(this);
};</source>

Custom Objects and Events
<source lang="javascript">
userPicker.onuserselected = function(ev) {
console.log(ev.user + " chosen.");
};
</source>

==== Event Listener Interface ====
<source lang="javascript">
el.addEventListener("click", function(ev) {
alert("clicked");
}, false);
</source>

Custom objects
<source lang="javascript">
userPicker.addCallback("onuserselected", function(ev) {
console.log(ev.user + " chosen.");
});
</source>

98.210.197.51: /* parseInt(s, radix) */

There are five primitive types in JavaScript: Null, Undefined, Boolean, String, Number.

Various operations in JavaScript require conversion to and from primitive values.

=== Converting to Boolean ===
When evaluating any expression that requires a boolean value, the expression must be converted into a boolean using the internal <nowiki>[[ToBoolean]]</nowiki>.

For example:
<source lang="javascript">
var n = 0;
if(n) { // false
}

var t = !""; // true. Empty string is falsy.
var f = !"f"; // false. Non-empty strings are not falsy.
Boolean(""); // false.
</source>

All numbers boolean-convert to true except for the following: <code>+/-0</code> and <code>NaN</code>

Boolean operators use type-conversion for the evaluation of their left hand side operands.
<source lang="javascript">
1 && 0; // 0.
"" || 0; // 0.
null || undefined; // undefined.
undefined || 1; // 1.
NaN || 0; // 0;
</source>

All falsy values:
<source lang="javascript">
false
""
null
undefined
0
NaN
</source>

All other primitive values and all objects are truthy.

=== Converting to String ===
With the <code>+</code> operator, when either operand is a string, concatenation is performed.

All native objects have a toString method. Number.prototype.toString(base) is special in that it takes a <code>base</code> parameter.

<source lang="javascript">
15..toString(16)
</source>

<source lang="javascript">
String(15); // Calls ToPrimitive(input argument, hint String).
</source>

=== Object to Primitive ===
Whenever the <code>+</code> operator is used, the operands must be converted into primitive values. First, the interpreter calls the object's valueOf to get a primitive value. If the result is a primitive value, then that value is used. '''Example:'''

<source lang="javascript">
var o = {
valueOf : function() { return 1; }
};
o + 1; // 2.
</source>

Otherwise, if <code>''o''.valueOf</code> results in an object —and <code>Object.prototype.valueOf</code> does — the object's <code>toString</code> is called.
<source lang="javascript">
var o = { toString : function() { return "1"; } };
o + 1; // "11".
</source>

'''Example:''' [http://jsbin.com/eTAQaNoX/2/edit toString, valueOf, and concatenation]

=== Converting to Number ===
Converting strings is a very common requirement and many approaches can be used. Any mathematical operator except the concatenation/addition operator will force type-conversion to number.

== parseInt(s, radix) ==

To force use of a particular base, use the radix parameter:
<source lang="javascript">parseInt("09", base) // base from 2 to 36.</source>

If <code>radix</code> is omitted, the base is determined by the contents of the string. Any string beginning with <code>0x</code> or <code>0X</code> represents a hexadecimal number. A string beginning with a leading 0 may, in older implementations, be parsed as octal (as if raxix were 8), in ECMA-262 Ed 3 (octal digits are 0-7). If string <code>09</code> is converted to <code>0</code>.

<source lang="javascript">
var t = "0xf";
Number(t); // 15
+t; // 15
</source>

=== Primitive to Object ===
Property access operation on string, number, and boolean primitives results in the creation of a temporary object.
<source lang="javascript">
// Primitive to Object conversion.
true.toString(); // Boolean Object.
1.2.valueOf(); // Number object.
" foo ".trim(); // String Object.

// null.toString(); // TypeError
// undefined.toString(); // TypeError
</source>

=== Type Checking ===
==== The typeof Operator ====
<source lang="javascript">
typeof someval;
</source>

<table>
<tr>
<th>Type <th>Result
<tr><td>Undefined <td>"undefined"
<tr><td>Null <td>"object"
<tr><td>Boolean <td>"boolean"
<tr><td>Number <td>"number"
<tr><td>String <td>"string"
<tr><td>Object (native and doesn't implement <nowiki>[[Call]]</nowiki>) <td>"object"
<tr><td>Object (native or host and implements <nowiki>[[Call]]</nowiki>) <td>"function"

98.210.197.51: /* Interface Based Design */

== Interface Based Design ==
Using a common <b>interface</b>, different Event registries handle different types of event registration:
# Event handler properties. Browser agnostic.
# Dom Event callback registration methods, considering delegation, IE event model, browser anomalies.

'''Source:''' https://github.com/GarrettS/EventPublisher

==== DOM Events ====
DOM events need an adapter for addressing the great difference in old IE's event model, with <code>attachEvent</code> and getting an event's <code>target</code>.
==== Custom Events ====
Custom Events are user defined so do not need any adapter.

===Encapsulate the Parts that Vary===
Event handler properties are useful for custom events and DOM events.

For DOM compatibility, it is often necessary to have methods that will handle old IE event model or work with delegate listeners (See: [http://www.w3.org/TR/DOM-Level-3-Events/#event-flow DOM Event Flow]).

=== Common Interface ===
Each interface shares the following methods:
<source lang="javascript">
// Static:
get(src, sEvent); // Gets an event publisher.
addCallback(src, sEvent, callback);
removeCallback(o, type, cb); // useCapture for DOM.

// Instance:
eventPublisher.addCallback(sEvent, callback);
eventPublisher.removeCallback(sEvent, callback);
</source>

The DOM events interface has an additional parameter, `useCapture` for the capturing phase of the Event phase in <code>removeCallback</code>, used internally.

==== Event Handler Properties ====
Each event is a property name. The value is a function or null. The pattern works equally well for custom events on user-defined objects and DOM events.

DOM Elements
<source lang="javascript">
el["onclick"] = function(ev) {
alert(this);
};</source>

Custom Objects and Events
<source lang="javascript">
userPicker.onuserselected = function(ev) {
console.log(ev.user + " chosen.");
};
</source>

==== Event Listener Interface ====
<source lang="javascript">
el.addEventListener("click", function(ev) {
alert("clicked");
}, false);
</source>

Custom objects
<source lang="javascript">
userPicker.addCallback("onuserselected", function(ev) {
console.log(ev.user + " chosen.");
});

# Dom Event callback registration methods, considering delegation, IE event model, browser anomalies.

https://github.com/GarrettS/EventPublisher

==== DOM Events ====
DOM events need an adapter for addressing the great difference in old IE's event model, with <code>attachEvent</code> and getting an event's <code>target</code>.
==== Custom Events ====
Custom Events are user defined so do not need any adapter.

===Encapsulate the Parts that Vary===
Event handler properties are useful for custom events and DOM events.

For DOM compatibility, it is often necessary to have methods that will handle old IE event model or work with delegate listeners (See: [http://www.w3.org/TR/DOM-Level-3-Events/#event-flow DOM Event Flow]).

=== Common Interface ===
Each interface shares the following methods:
<source lang="javascript">
// Static:
get(src, sEvent); // Gets an event publisher.
addCallback(src, sEvent, callback);
removeCallback(o, type, cb); // useCapture for DOM.

// Instance:
eventPublisher.addCallback(sEvent, callback);
eventPublisher.removeCallback(sEvent, callback);
</source>

The DOM events interface has an additional parameter, `useCapture` for the capturing phase of the Event phase in <code>removeCallback</code>, used internally.

==== Event Handler Properties ====
Each event is a property name. The value is a function or null. The pattern works equally well for custom events on user-defined objects and DOM events.

DOM Elements
<source lang="javascript">
el["onclick"] = function(ev) {
alert(this);
};</source>

Custom Objects and Events
<source lang="javascript">
userPicker.onuserselected = function(ev) {
console.log(ev.user + " chosen.");
};
</source>

==== Event Listener Interface ====
<source lang="javascript">
el.addEventListener("click", function(ev) {
alert("clicked");
}, false);
</source>

Custom objects
<source lang="javascript">
userPicker.addCallback("onuserselected", function(ev) {
console.log(ev.user + " chosen.");
});
</source>

JavaScript/Notes/TypeConversion

98.210.197.51: /* Converting to String */

There are five primitive types in JavaScript: Null, Undefined, Boolean, String, Number.

Various operations in JavaScript require conversion to and from primitive values.

=== Converting to Boolean ===
When evaluating any expression that requires a boolean value, the expression must be converted into a boolean using the internal <nowiki>[[ToBoolean]]</nowiki>.

For example:
<source lang="javascript">
var n = 0;
if(n) { // false
}

var t = !""; // true. Empty string is falsy.
var f = !"f"; // false. Non-empty strings are not falsy.
</source>

All numbers boolean-convert to true except for the following: <code>+/-0</code> and <code>NaN</code>

Boolean operators use type-conversion for the evaluation of their left hand side operands.
<source lang="javascript">
1 && 0; // 0.
"" || 0; // 0.
null || undefined; // undefined.
undefined || 1; // 1.
NaN || 0; // 0;
</source>

All falsy values:
<source lang="javascript">
false
""
null
undefined
0
NaN
</source>

All other primitive values and all objects are truthy.

=== Converting to String ===
With the <code>+</code> operator, when either operand is a string, concatenation is performed.

All native objects have a toString method. Number.prototype.toString(base) is special in that it takes a <code>base</code> parameter.

<source lang="javascript">
15..toString(16)
</source>

=== Object to Primitive ===
Whenever the <code>+</code> operator is used, the operands must be converted into primitive values. First, the interpreter calls the object's valueOf to get a primitive value. If the result is a primitive value, then that value is used. '''Example:'''

<source lang="javascript">
var o = {
valueOf : function() { return 1; }
};
o + 1; // 2.
</source>

Otherwise, if <code>''o''.valueOf</code> results in an object —and <code>Object.prototype.valueOf</code> does — the object's <code>toString</code> is called.
<source lang="javascript">
var o = { toString : function() { return "1"; } };
o + 1; // "11".
</source>

=== Converting to Number ===
Converting strings is a very common requirement and many approaches can be used. Any mathematical operator except the concatenation/addition operator will force type-conversion to number.

== parseInt(s, radix) ==

To force use of a particular base, use the radix parameter: <code>parseInt("09", base)</code> (from 2 to 36).

If <code>radix</code> is omitted, the base is determined by the contents of the string. Any string beginning with <code>0x</code> or <code>0X</code> represents a hexadecimal number. A string beginning with a leading 0 may, in older implementations, be parsed as octal (as if raxix were 8), in ECMA-262 Ed 3 (octal digits are 0-7). If string <code>09</code> is converted to <code>0</code>.

=== Primitive to Object ===
Property access operation on string, number, and boolean primitives results in the creation of a temporary object.
<source lang="javascript">
// Primitive to Object conversion.
true.toString(); // Boolean Object.
1.2.valueOf(); // Number object.
" foo ".trim(); // String Object.

// null.toString(); // TypeError
// undefined.toString(); // TypeError
</source>

=== Type Checking ===
==== The typeof Operator ====
<source lang="javascript">
typeof someval;
</source>

98.210.197.51: /* The typeof Operator */

There are five primitive types in JavaScript: Null, Undefined, Boolean, String, Number.

Various operations in JavaScript require conversion to and from primitive values.

=== Converting to Boolean ===
When evaluating any expression that requires a boolean value, the expression must be converted into a boolean using the internal <nowiki>[[ToBoolean]]</nowiki>.

For example:
<source lang="javascript">
var n = 0;
if(n) { // false
}

var t = !""; // Empty string is falsy.
var f = !"f"; // Non-empty strings are not falsy.
</source>

All numbers boolean-convert to true except for the following: <code>+/-0</code> and <code>NaN</code>

Boolean operators use type-conversion for the evaluation of their left hand side operands.
<source lang="javascript">
1 && 0; // 1.
"" || 0; // 0.
null || undefined; // undefined.
undefined || 1; // 1.
NaN || 0; // 0;
</source>

All falsy values:
<source lang="javascript">
false
""
null
undefined
0
NaN
</source>

All other primitive values and all objects are truthy.

=== Converting to String ===
When either operand is a string, concatenation is performed.

=== Object to Primitive ===
Whenever the <code>+</code> operator is used, the operands must be converted into primitive values. First, the interpreter calls the object's valueOf to get a primitive value. If the result is a primitive value, then that value is used. '''Example:'''

<source lang="javascript">
var o = {
valueOf : function() { return 1; }
};
o + 1; // 2.
</source>

Otherwise, if <code>''o''.valueOf</code> results in an object —and <code>Object.prototype.valueOf</code> does — the object's <code>toString</code> is called.
<source lang="javascript">
var o = { toString : function() { return "1"; } };
o + 1; // "11".
</source>

=== Converting to Number ===
Converting strings is a very common requirement and many methods can be used. Any mathematical operator except the concatenation/addition operator will force type-conversion to number.

=== Primitive to Object ===
Property access operation on string, number, and boolean primitives results in the creation of a temporary object.
<source lang="javascript">
true.toString(); // Boolean Object.
1.2.valueOf(); // Number object.
" foo ".trim(); // String Object.

// null.toString(); // TypeError
// undefined.toString(); // TypeError
</source>

=== Type Checking ===
==== The typeof Operator ====
<source lang="javascript">
typeof someval;
</source>

<th>Type <th>Result

<tr><td>Null <td>"object"
<tr><td>Boolean <td>"boolean"
<tr><td>Number <td>"number"

Official, Semi-Official, one-off and other events at the Noisebridge space.


=Event Calendar=
Not all events make it onto this calendar. Many events only make it to the Discussion or Announcements [[Mailinglist | mailing lists]], [[IRC]] or in person at [[:Category:Meeting_Notes | Tuesday meetings]]. Best of all, Noisebridge is about people getting together at the space in San Francisco to do stuff........like in person(?) DO pay attention, as some events just arise organically from the bottom up!

If you'd like to host an event yourself, we recommend bringing in at least one Noisebridge member, and getting advice on [[Hosting_an_Event|hosting an event]] at Noisebridge.

You should view the [https://www.google.com/calendar/embed?src=1uesj915rces4cbmcr8j3sg8t0%40group.calendar.google.com&ctz=America/Los_Angeles Google Calendar].
To post Google Calendar entries for your event or to gain access to do so for yourself, ask on the [https://www.noisebridge.net/mailman/listinfo/noisebridge-discuss Noisebridge-Discuss] (sometimes known as the Noisebridge "Disgust") mailing list.

JavaScript/Notes/Prototype

2014-01-06T03:43:41Z

98.210.197.51:

== Prototype Chain ==

<blockquote>Every object created by a constructor has an implicit reference (called the object’s prototype) to the value of its constructor’s “prototype” property. Furthermore, a prototype may have a non-null implicit reference to its prototype, and so on; this is called the prototype chain. When a reference is made to a property in an object, that reference is to the property of that name in the first object in the prototype chain that contains a property of that name. In other words, first the object mentioned directly is examined for such a property; if that object contains the named property, that is the property to which the reference refers; if that object does not contain the named property, the prototype for that object is examined next; and so on. ([http://ecma-international.org/ecma-262/5.1/#sec-4.2.1 §4.2.1 Objects]).
</blockquote>

=== Constructors ===
<source lang="javascript">
function MyConstructor() {

}

var anObj = new MyConstructor;
</source>

Every user-defined function has a prototype property, provided by the implementation. The prototype property that is provided by the implementation has a <code>constructor</code> property that points back to the constructor function.

<source lang="javascript">
function MyConstructor() {

}

alert(MyConstructor.prototype.constructor);
</source>

The prototype property is used for prototype inheritance of shared properties. When any function is used in a new Expression, a new object is created and given a link to the constructor function's `prototype` property.

<blockquote>
<h3>8.6.2 Internal Properties and Methods</h3>

<p>
All objects have an internal property called <nowiki>[[Prototype]]</nowiki>. The value of this property is either null or an object and is used for implementing inheritance. Whether or not a native object can have a host object as its <nowiki>[[Prototype]]</nowiki> depends on the implementation. Every <nowiki>[[Prototype]]</nowiki> chain must have finite length (that is, starting from any object, recursively accessing the <nowiki>[[Prototype]]</nowiki> internal property must eventually lead to a null value). Named data properties of the <nowiki>[[Prototype]]</nowiki> object are inherited (are visible as properties of the child object) for the purposes of get access, but not for put access. Named accessor properties are inherited for both get access and put access.</p>
</blockquote>

<source lang="javascript">
function MyConstructor() {

}

MyConstructor.prototype = {
toString : function() {
return "[object MyConstructor]";
}
};

alert(new MyConstructor().toString())
</source>
As shown in the above example, any function's prototype property can be replaced by any user-defined object.

<source lang="javascript">
function MyConstructor(name) {
}

MyConstructor.prototype = {
toString : function() {
return "[object MyConstructor]";
}
};

function MySubclass(name) { }
MySubclass.prototype = new MyConstructor;
</source>

== Subclassing ==
<source lang="javascript">
// Base class.
function MyConstructor(name) {
this.name = name;
}

// Prototype.
MyConstructor.prototype = {
toString : function() {
return "[object MyConstructor]";
}
};

// Subclass.
function MySubclass(name) {
// Call super constructor.
MyConstructor.call(this, name);
}
</source>

== Shadowing ==
(whiteboard diagram)

== Object.create ==
<source lang="javascript">// Extend prototype.
MySubclass.prototype = Object.create(MyConstructor.prototype);

MySubclass.prototype.valueOf = function() {
return this.name;
};
</source>

JavaScript/Notes/Scope

2013-12-19T19:44:13Z

98.210.197.51: /* Block Scope */

=Scope Chain and Identifier Resolution.=
A "closure" is function scope that has a binding to its containing scope.

== Example ==
[http://jsbin.com/OxOSObuc/1/edit jsbin]
<source lang="javascript">
(function () {
var currentScope = 1, one = 'scope1';
alert(currentScope);
(function () {
var currentScope = 2, two = 'scope2';
alert(currentScope);
(function () {
var currentScope = 3, three = 'scope3';
alert(currentScope);
alert(one + two + three); // climb up the scope chain to get one and two
}());
}());
}());</source>

== Example ==
[http://jsbin.com/OxOSObuc/1/edit jsbin]
<source lang="javascript">
function outer() {
var secret = 1;
function inner() {
return secret;
}
return inner;
}

var inner = outer();
var result = inner();
console.log(result); // explain the result.
</source>

== Block Scope ==
Normally, the only way to create scope in JavaScript is by creating a function. However, a little known anomaly is that the catch block augments the scope with a new object.
<source lang="javascript">
function x() {
var result = typeof x;
try {
y; // ReferenceError
} catch(x) {
result = [result, x];
}
result.push(typeof x);
alert(result);
}
</source>
http://jsbin.com/EveMAVIP/1/edit
<h3>Catch Block Identifier</h3>
In the above code, a new DeclarativeEnvironment is dynamically created when the catch block is entered, with the Identifier `x` being added to its scope, and that scope being used for the duration of the catch block. See: [http://ecma-international.org/ecma-262/5.1/#sec-12.14 Ecma-262 § 12.14].

== Variable Scope Inside function ==
Richard Cornford explains Variable Instantiation, as defined in ECMA-262 r3.
http://bytes.com/topic/javascript/answers/556357-variable-scope-inside-function-did-i-get-correctly#post2171544

== Declaration Binding Instantiation ==
[http://www.ecma-international.org/ecma-262/5.1/#sec-10.5 § 10.5]
Every execution context has an associated VariableEnvironment. Variables and functions declared in ECMAScript code evaluated in an execution context are added as bindings in that VariableEnvironment’s Environment Record. For function code, parameters are also added as bindings to that Environment Record.

From [https://groups.google.com/forum/#!topic/jsmentors/JnHM3Pvesp8 global object property access].
<blockquote>
Consider the following "weird" behavior with the global object:
<source lang="javascript">
console.log(window.foo); // this returns undefined
console.log(this.foo); // this returns undefined
console.log(foo); // this is a reference error
</source>

Accessing a non existent property on an object should return
undefined... which accounts for the first two cases... but whats going
on in the third case?
</blockquote>

the ECMAScript specification on
<code>[http://www.ecma-international.org/ecma-262/5.1/#sec-15.11.6.3 ReferenceError]</code> explains that <code>ReferenceError</code> is also thrown in strict mode when making an assignment to an undeclared identifer.

<source lang="javascript">
(function(){ "use strict"; erwt = 1; })(); // ReferenceError
</source>

Back to the example, getting a property off an object, the prototype chain is
searched. When that happens, if the property is not found, then
<code>undefined</code> results.

But with scope chain resolution, when the property is not resolved, an
error results.

<blockquote style="white-space:pre">
| 11.1.2 Identifier Reference
| An Identifier is evaluated by performing Identifier Resolution
| as specified in 10.3.1. The result of evaluating an Identifier
| is always a value of type Reference.
</blockquote>
...
<blockquote style="white-space:pre">
| 10.3.1 Identifier Resolution
| Identifier resolution is the process of determining the binding of an
| Identifier using the <code>LexicalEnvironment</code> of the running execution context.
</blockquote>

<blockquote style="white-space:pre">
> console.log(foo); // this is a reference error
>
</blockquote>

<p>Identifier <code>foo</code> is resolved to a Reference with null as the base
object. In ES5, it looks as if it is a Reference with base object as
<code>undefined</code>. With either spec, the result will be the same:
<code>ReferenceError</code>. ES5 gets a little fancy with the explanation.

<blockquote style="white-space:pre">
> The Mozilla docs on Reference error simply state:

They mean that when you try and get the value of an Identifier in a
PrimaryExpression and the Identifier is not resolved, then the base
object is null (or now <code>undefined</code>) that the attempt to get at the
value is going to result in a <code>ReferenceError</code>.

So when you have an Expression like:
<pre>
console.log(foo);
</pre>
or even just a PrimaryExpression:
<pre>
foo // a PrimaryExpression.
</pre>

Identifier <code>foo</code> must be first resolved. The base object for that
value is null (or so"undefined") and the when the expression is
evaluated, it tries to get the value, and then finds the base object
is null and throws a ReferenceError is thrown.

| 8.7.1 GetValue (V)
|
| 1. If Type(V) is not Reference, return V.
| 2. Let base be the result of calling GetBase(V).
| 3. If IsUnresolvableReference(V), throw a ReferenceError exception.

...

| IsUnresolvableReference(V). Returns true if the base value
| is undefined and false otherwise.

The MDC docs might not say it, and you didn't ask, either, but in
strict code, assignment to undeclared Identifier will result in
referenceerror too.

<blockquote style="white-space:pre">
> I realize accessing a non existent property on an object should return
> undefined... which accounts for the first two cases... but whats going
> on in the third case?
</blockquote>

An Identifier resolution was performed on the scope chain. Just
remember the difference when getting a property fails: With object
properties - the prototype chain is used and the result is undefined.
With unqualified Identifiers, the scope chain is searched in the
result is ReferenceError.

==Omitting var in VariableDeclaration==
Assignment without var is not a variable declaration.
<pre>
foo = 1;
</pre>

The identifier foo must be resolved up the scope chain (see 11.13.1
Simple Assignment, also below). If foo is not found, a foo property is
created on the global object (see 8.7.2 <code>PutValue</code>).

This can cause further problems in IE with IE's global scope polluter. See: [https://groups.google.com/forum/#!msg/comp.lang.javascript/K3PD0gJgUxY/0R0OZvHs2K4J Extra Properties: The Element Id Resolver Object]

<pre>
11.13.1 Simple Assignment (= )
The production AssignmentExpression : LeftHandSideExpression =
AssignmentExpression is evaluated as follows:
1. Evaluate LeftHandSideExpression.
2. Evaluate AssignmentExpression.
3.Call GetValue(Result(2)).
4.Call PutValue(Result(1), Result(3)).
5.Return Result(3).
</pre>

Step 4 leads to <code>PutValue(foo, 1)</code>

<pre>
8.7.2 PutValue(V, W)
1. If Type(V) is not Reference, throw a ReferenceError exception.
2. Call GetBase(V).
3. If Result(2) is null, go to step 6.
4. Call the [[Put]] method of Result(2), passing GetPropertyName(V)
for the property name and W for the value.
5. Return.
6. Call the [[Put]] method for the global object, passing
GetPropertyName(V) for the property name and W for the value.
7. Return.
</pre>

Step 2, <code>GetBase(v)</code> is <code>null</code>, so that leads to step 6. That leads to
<code><nowiki>[[Put]]</nowiki></code> (foo, 1) on the global object.

<pre>
8.6.2.2 [[Put]](P, V)
When the [[Put]] method of O is called with property P and value V,
the following steps are taken:
1. Call the [[CanPut]] method of O with name P.
2. If Result(1) is false, return.
3. If O doesn't have a property with name P, go to step 6.
4. Set the value of the property to V. The attributes of the
property are not changed.
5. Return.
6. Create a property with name P, set its value to V and give it
empty attributes.
7. Return.
Note, however, that if O is an Array object, it has a more elaborate
[[Put]] method (15.4.5.1).
</pre>
Note step 6: Create a property with name P, set its value to V and give
it empty attributes.

Global object properties (user-defined ones, at least) are <nowiki>[[Configurable]]</nowiki>,
variables, global or otherwise, are not.

User-defined properties are, by default, <nowiki>[[Configurable]]</nowiki>, which means that they can be deleted.

If code is eval code, then let configurableBindings be true else let configurableBindings be false.

== Ambitions ==

=== Guitar Improvisation Class ===
<p>'''Web:'''
[http://chordcycles.com ChordCycles], learning and knowledge.
</p>

<p>I like to share my art and mind and discipline with others of all levels. I can teach in my own apartment or in a room that is secure and where I can make some noise.</p>

<p>Berklee: Consumerism and putting money and marketing before education. Little emphasis on performance, even for performance majors.
</p>

<p>
To make the school community-driven, cooperative, and affordable. If you are broke but can play and show up on time, you may be accommodated.</p>

<p>
Kids who went to Berklee because they were inspired by Steve Vai got "financial aid" and student loans only to accrue $80,000+ student loan debt, which they slavishly repay over the next 10-20 years, working a job that requires a "bachelor's degree".
</p>

<p>
There is [http://www.yelp.com/biz/berklee-college-of-music-boston#hrid:KOAri3u0lGhUiO-dbk-Y-g no good reason] why the cost of music school must be so high.
</p>

=== JavaScript Class ===
Teaching [[JavaScript]].

=== Food justice - Public Growing ===
<p>Based on [http://en.wikipedia.org/wiki/Voluntaryism voluntaryism] principles of taking neither government nor corporate money, I am trying to build a web application for allowing people to grow food in open, public space for free. And I need help!</p>

<p>
We need someone to do the database and object model and Node.js hosting. If you want to get involved, please contact my gmail: dhtmlkitchen.
</p>

== Stuff I like ==
=== Guitar ===
<p>
I like to play and teach. Some of my musical influence include J.S. Bach, Paul Gilbert, and Yngwie Malmsteen.
</p>

</p>

=== Nutrition and Health ===
<p>I am interested in organic, medicinal foods, local foods, food sovereignty raw milk, pastured eggs.</p>

== Skills, Things I Do ==
=== JavaScript ===
<p>I wrote many articles on dhtmlkitchen.com, covering advanced subjects that tend to deal the language itself, as well as patterns and object oriented javascript, including higher-order functions, EventRegistry, AbstractFactory, Encapsulation.
</p>

JavaScript/Notes/Scope

2013-12-16T15:37:43Z

98.210.197.51: /* Example */

=Scope Chain and Identifier Resolution.=
A "closure" is function scope that has a binding to its containing scope.

== Example ==
[http://jsbin.com/OxOSObuc/1/edit jsbin]
<source lang="javascript">
(function () {
var currentScope = 1, one = 'scope1';
alert(currentScope);
(function () {
var currentScope = 2, two = 'scope2';
alert(currentScope);
(function () {
var currentScope = 3, three = 'scope3';
alert(currentScope);
alert(one + two + three); // climb up the scope chain to get one and two
}());
}());
}());</source>

== Example ==
[http://jsbin.com/OxOSObuc/1/edit jsbin]
<source lang="javascript">
function outer() {
var secret = 1;
function inner() {
return secret;
}
return inner;
}

var inner = outer();
var result = inner();
console.log(result); // explain the result.
</source>

== Block Scope ==
Normally, the only way to create scope in JavaScript is by creating a function. However, a little known anomaly is that the catch block augments the scope with a new object.
<source lang="javascript">
function x() {
var result = typeof x;
try {
y;
} catch(x) {
x = 10;
result = [result, x];
}
result.push(typeof x);
alert(result);
}
</source>

== Variable Scope Inside function ==
Richard Cornford explains Variable Instantiation, as defined in ECMA-262 r3.
http://bytes.com/topic/javascript/answers/556357-variable-scope-inside-function-did-i-get-correctly#post2171544

== Declaration Binding Instantiation ==
[http://www.ecma-international.org/ecma-262/5.1/#sec-10.5 § 10.5]
Every execution context has an associated VariableEnvironment. Variables and functions declared in ECMAScript code evaluated in an execution context are added as bindings in that VariableEnvironment’s Environment Record. For function code, parameters are also added as bindings to that Environment Record.

From [https://groups.google.com/forum/#!topic/jsmentors/JnHM3Pvesp8 global object property access].
<blockquote>
Consider the following "weird" behavior with the global object:
<source lang="javascript">
console.log(window.foo); // this returns undefined
console.log(this.foo); // this returns undefined
console.log(foo); // this is a reference error
</source>

Accessing a non existent property on an object should return
undefined... which accounts for the first two cases... but whats going
on in the third case?
</blockquote>

the ECMAScript specification on
<code>[http://www.ecma-international.org/ecma-262/5.1/#sec-15.11.6.3 ReferenceError]</code> explains that <code>ReferenceError</code> is also thrown in strict mode when making an assignment to an undeclared identifer.

<source lang="javascript">
(function(){ "use strict"; erwt = 1; })(); // ReferenceError
</source>

Back to the example, getting a property off an object, the prototype chain is
searched. When that happens, if the property is not found, then
<code>undefined</code> results.

But with scope chain resolution, when the property is not resolved, an
error results.

<blockquote style="white-space:pre">
| 11.1.2 Identifier Reference
| An Identifier is evaluated by performing Identifier Resolution
| as specified in 10.3.1. The result of evaluating an Identifier
| is always a value of type Reference.
</blockquote>
...
<blockquote style="white-space:pre">
| 10.3.1 Identifier Resolution
| Identifier resolution is the process of determining the binding of an
| Identifier using the <code>LexicalEnvironment</code> of the running execution context.
</blockquote>

<blockquote style="white-space:pre">
> console.log(foo); // this is a reference error
>
</blockquote>

<p>Identifier <code>foo</code> is resolved to a Reference with null as the base
object. In ES5, it looks as if it is a Reference with base object as
<code>undefined</code>. With either spec, the result will be the same:
<code>ReferenceError</code>. ES5 gets a little fancy with the explanation.

<blockquote style="white-space:pre">
> The Mozilla docs on Reference error simply state:
>
> A ReferenceError is thrown when trying to dereference a variable that
> has not been declared.
>
</blockquote>

They mean that when you try and get the value of an Identifier in a
PrimaryExpression and the Identifier is not resolved, then the base
object is null (or now <code>undefined</code>) that the attempt to get at the
value is going to result in a <code>ReferenceError</code>.

So when you have an Expression like:
<pre>
console.log(foo);
</pre>
or even just a PrimaryExpression:
<pre>
foo // a PrimaryExpression.
</pre>

Identifier <code>foo</code> must be first resolved. The base object for that
value is null (or so"undefined") and the when the expression is
evaluated, it tries to get the value, and then finds the base object
is null and throws a ReferenceError is thrown.

| 8.7.1 GetValue (V)
|
| 1. If Type(V) is not Reference, return V.
| 2. Let base be the result of calling GetBase(V).
| 3. If IsUnresolvableReference(V), throw a ReferenceError exception.

...

| IsUnresolvableReference(V). Returns true if the base value
| is undefined and false otherwise.

The MDC docs might not say it, and you didn't ask, either, but in
strict code, assignment to undeclared Identifier will result in
referenceerror too.

<blockquote style="white-space:pre">
> I realize accessing a non existent property on an object should return
> undefined... which accounts for the first two cases... but whats going
> on in the third case?
</blockquote>

An Identifier resolution was performed on the scope chain. Just
remember the difference when getting a property fails: With object
properties - the prototype chain is used and the result is undefined.
With unqualified Identifiers, the scope chain is searched in the
result is ReferenceError.

==Omitting var in VariableDeclaration==
Assignment without var is not a variable declaration.
<pre>
foo = 1;
</pre>

The identifier foo must be resolved up the scope chain (see 11.13.1
Simple Assignment, also below). If foo is not found, a foo property is
created on the global object (see 8.7.2 <code>PutValue</code>).

This can cause further problems in IE with IE's global scope polluter. See: [https://groups.google.com/forum/#!msg/comp.lang.javascript/K3PD0gJgUxY/0R0OZvHs2K4J Extra Properties: The Element Id Resolver Object]

<pre>
11.13.1 Simple Assignment (= )
The production AssignmentExpression : LeftHandSideExpression =
AssignmentExpression is evaluated as follows:
1. Evaluate LeftHandSideExpression.
2. Evaluate AssignmentExpression.
3.Call GetValue(Result(2)).
4.Call PutValue(Result(1), Result(3)).
5.Return Result(3).
</pre>

Step 4 leads to <code>PutValue(foo, 1)</code>

<pre>
8.7.2 PutValue(V, W)
1. If Type(V) is not Reference, throw a ReferenceError exception.
2. Call GetBase(V).
3. If Result(2) is null, go to step 6.
4. Call the [[Put]] method of Result(2), passing GetPropertyName(V)
for the property name and W for the value.
5. Return.
6. Call the [[Put]] method for the global object, passing
GetPropertyName(V) for the property name and W for the value.
7. Return.
</pre>

Step 2, <code>GetBase(v)</code> is <code>null</code>, so that leads to step 6. That leads to
<code><nowiki>[[Put]]</nowiki></code> (foo, 1) on the global object.

<pre>
8.6.2.2 [[Put]](P, V)
When the [[Put]] method of O is called with property P and value V,
the following steps are taken:
1. Call the [[CanPut]] method of O with name P.
2. If Result(1) is false, return.
3. If O doesn't have a property with name P, go to step 6.
4. Set the value of the property to V. The attributes of the
property are not changed.
5. Return.
6. Create a property with name P, set its value to V and give it
empty attributes.
7. Return.
Note, however, that if O is an Array object, it has a more elaborate
[[Put]] method (15.4.5.1).
</pre>
Note step 6: Create a property with name P, set its value to V and give
it empty attributes.

Global object properties (user-defined ones, at least) are <nowiki>[[Configurable]]</nowiki>,
variables, global or otherwise, are not.

User-defined properties are, by default, <nowiki>[[Configurable]]</nowiki>, which means that they can be deleted.

If code is eval code, then let configurableBindings be true else let configurableBindings be false.
