This page lists some interesting coding patterns that we may or may not use in our code.

Self Executing Functions

This is already a classic. Using a self calling function declaration to isolate its contents from the current scope, avoiding polluting it with variables.

(function()
{ 
	... 
})();

Objects with Private Stuff

var myObj = function()
{ 
	// Private variables.
	var privateVar = 10;

	var privateFunction = function()
	{ 
        ... 
	};

	// Public stuff.
	return { 
      	publicMethod : function()
		{ 
			// May access privateVar or privateFunction.
        		... 
		}
	};
}();

For Loops and Length

The "length" property should not be checked on each "for" cycle. The following construction should be used instead:

 
for ( var i = 0, len = list.length ; i < len ; i++ } 
{ 
        ... 
}
