Features

• Based on Javascript Module Pattern (Asynchronous Module Definitions)
• Works by embedding module inside a function.
• Enforces tighter encapsulation.
• Allows non-javascript resoures with loader plugins.
• Wires dependencies based on configuration.

When to use RequireJS?

• For Large Applications
• Applications with lots of different libraries.
• When scripts contain shared functionality.
• Create and load custom frameworks.
• Reduce Spaghetti Code.

define(['dep1','dep2'] , function ($) {
    //Return the public API for your module.
    var api = {
    	function () {
    	//API behavior here
		};
	};
	return api;
});

require(['dep1'], function(dep1) {
	//Use the defined public api here
	};
);
