JS.Class Ruby-like classes for JavaScript

Patterns

The class.js file defines JS.Class, JS.Interface, JS.Module and JS.Singleton; generic components to help you build specific functionality. The other files in the download implement a number of commonly used design patterns and reusable components that provide pre-built solutions to common coding problems.

JavaScript’s power and flexibility allow parts of the implementation of some design patterns to be automated. The design pattern implementations presented here allow you to use design patterns to create robust code, letting you focus on your specific problem rather on on the details of the pattern you are using.

The components and patterns provided by JS.Class are listed in the sidebar. They all provide some concrete implementation for solving specific problems, which is what sets them apart from the class.js components. The files contained in the download are as follows:

• command.js – defines JS.Command and JS.Command.Stack
• comparable.js – defines JS.Comparable
• decorator.js – defines JS.Decorator
• enumerable.js – defines JS.Enumerable
• forwardable.js – defines JS.Forwardable
• linked_list.js – defines JS.LinkedList.Doubly.Circular
• method_chain.js – defines JS.MethodChain
• observable.js – defines JS.Observable
• proxy.js – defines JS.Proxy.Virtual
• ruby.js – defines JS.Ruby, a Ruby-like DSL for writing classes
• state.js – defines JS.State

• Inheritance and callSuper
• Static/class methods
• Mixins
• include and extend
• Singleton methods
• Method binding
• Callbacks and hooks
• Modules
• Type checking, the class tree
• Interfaces
• Singletons
