You down with OOP? - Yeah you know me!
Introduction[edit | edit source]
Overview: JavaScript Language Fundamentals and design patterns for web programming. See JavaScript.
Teacher: Garrett Smith
Resources Web Development Resources
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:
ECMAScript defines the standard for JavaScript (§ 1).
All references used in this class are linked from the Web Development Resources page.
Debugging[edit | edit source]
Browsers provide debuggers that can be launched from a breakpoint, the application's menu, keyboard shortcut, or the debugger keyword in the script.
Parameter Object[edit | edit source]
Passing around lists of parameters? Typechecking arguments? Stop doing that. Here's how to make your code clearer and less error-prone.
Type Conversion[edit | edit source]
There are five primitive types in JavaScript: Null, Undefined, Boolean, String, Number. Various operations in JavaScript require conversion to and from primitive values.
ClassName Swap[edit | edit source]
Event Delegation and the Cascade.
Functions[edit | edit source]
Functions are callable objects with an internal [[Scope]] property. Learn how to call functions and pass functions to other functions, where they can be later called.
Array Methods added to EcmaScript 5[edit | edit source]
Sort, map, filter, and more.
Prerequisite: Functions.
Prototype[edit | edit source]
The prototype chain is used by the engine for reading property resolution.
User-defined functions can be used to construct new objects. Objects have, on their prototype chain, the constructor's prototype.
Prerequisite: Functions.
Scope Chain and Identifier Resolution[edit | edit source]
This class covers closures.
Prerequisite: Functions.
Custom Events[edit | edit source]
Fire custom events from your own user-defined objects.
Prerequisite: Functions.
Prerequisite: Scope Chain and Identifier Resolution.
Singleton[edit | edit source]
Singleton with information hiding in function scope.
Prerequisite: Functions.
Prerequisite: Scope Chain and Identifier Resolution.
Interface-Based Design[edit | edit source]
Prerequisite: 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!
Event Notification System[edit | edit source]
An abstract system for event notification.
Prerequisite: Functions.
Prerequisite: Scope Chain and Identifier Resolution.
DOM Events Adapter[edit | edit source]
An system for DOM event notification, designed to handle delegation and specific event models.
Prerequisite: Functions.
Prerequisite: Scope Chain and Identifier Resolution.
Factory[edit | edit source]
The Factory pattern, the Decorator pattern, newApply, and the holy grail: Abstract Factory.
Prerequisite: Functions.
Prerequisite: Parameter Object.
Prerequisite: Scope Chain and Identifier Resolution.
PrivateProxy[edit | edit source]
The private proxy exposes a public interface object. This public interface object delegates some of its responsibility to a private instance.
Prerequisite: Factory.
Testing[edit | edit source]
Unit testing with YUI Test.
Promises[edit | edit source]
ECMAScript 6 Promises.
