'''Reference Conventions''':
Each section points to specific sections of the pertinent specification for any given subject matter, and for ECMAScript, with a linked section marker. For example: 
<blockquote><p>ECMAScript defines the standard for JavaScript ([http://ecma-international.org/ecma-262/5.1/#sec-1 &sect; 1]).</p></blockquote>

All references used in this class are linked from the [[Web Development Resources]] page.

== [[JavaScript/Notes/Debugging|Debugging]] ==
Browsers provide debuggers that can be launched from a breakpoint, the application's menu, keyboard shortcut, or the debugger keyword in the script.


== [[JavaScript/Notes/ParameterObject|Parameter Object]] == 
Passing around lists of parameters? Typechecking arguments? Stop doing that. Here's how to make your code clearer and less error-prone.


== [[JavaScript/Notes/TypeConversion|Type Conversion]] ==
There are five primitive types in JavaScript: Null, Undefined, Boolean, String, Number. Various operations in JavaScript require conversion to and from primitive values.


== [[JavaScript/Notes/ClassnameSwap|ClassName Swap]] ==
Event Delegation and the Cascade.


== [[JavaScript/Notes/Function|Functions]] == 
Functions are callable objects with an internal <nowiki>[[Scope]]</nowiki> property. Learn how to call functions and pass functions to other functions, where they can be later called.


== [[JavaScript/Notes/Array|Array Methods added to EcmaScript 5]]==
Sort, map, filter, and more.

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].


== [[JavaScript/Notes/Prototype|Prototype]] ==
The prototype chain is used by the engine for reading property resolution. By the developer, the prototype chain is used for defining defaults. And for [www.w3.org/TR/WebIDL/ WebIDL], the prototype chain is defined to describe native inheritance of host object interfaces.

User-defined functions can be used to construct new objects. Objects have, on their prototype chain, the constructor's prototype. 

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].

== [[JavaScript/Notes/Scope|Scope Chain and Identifier Resolution]]==
This class covers closures. 

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].


== [[JavaScript/Notes/CustomEvents|Custom Events]] ==
Fire custom events from your own user-defined objects.

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].

'''Prerequisite:''' [[JavaScript/Notes/Scope|Scope Chain and Identifier Resolution]].


== [[JavaScript/Notes/Singleton|Singleton]] ==
Singleton with information hiding in function scope.

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].

'''Prerequisite:''' [[JavaScript/Notes/Scope|Scope Chain and Identifier Resolution]].


== [[JavaScript/Notes/IBD|Interface-Based Design]] ==

'''Prerequisite:''' [[JavaScript/Notes/CustomEvents|Custom Events]].

Two Event Registry interface objects that share a similar signature, each with a different implementation detail suited for a specific task.  The Devil's in the details -- encapsulate them!


=== [[JavaScript/Notes/EventNotificationSystem|Event Notification System]]===
An abstract system for event notification.

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].

'''Prerequisite:''' [[JavaScript/Notes/Scope|Scope Chain and Identifier Resolution]].


=== [[JavaScript/Notes/DomEvents|DOM Events Adapter]]===
An system for DOM event notification, designed to handle delegation and specific event models.

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].

'''Prerequisite:''' [[JavaScript/Notes/Scope|Scope Chain and Identifier Resolution]].

== [[JavaScript/Notes/Factory|Factory]] ==
The Factory pattern, the Decorator pattern, newApply, and the holy grail: Abstract Factory.

'''Prerequisite:''' [[JavaScript/Notes/Function|Functions]].

'''Prerequisite:''' [[JavaScript/Notes/ParameterObject|Parameter Object]].

'''Prerequisite:''' [[JavaScript/Notes/Scope|Scope Chain and Identifier Resolution]].

== [[JavaScript/Notes/PrivateProxy|PrivateProxy]] ==
The private proxy exposes a public interface object. This public interface object delegates some of its responsibility to a private instance.

'''Prerequisite:''' [[JavaScript/Notes/Factory|Factory]].

== [[JavaScript/Notes/Testing|Testing]]==
Unit testing with YUI Test.

== [[JavaScript/Notes/Promises|Promises]] == 
ECMAScript 6 Promises.
