Snippet for cross platform javascript modules

Cross platform js modules

(function(){
	"use strict"; 
	var result = {}; // your javascript module
	if(typeof define !== undefined && typeof define.amd !== undefined ){
		define(function(){
			return result;
		});
	} else if(typeof module !== undefined && typeof module.exports !== undefined ){
		module.exports = result;
	} else {
		return result;	
	}
}());

of course that doesn't work because typeof returns a string always and your comparisons are against undefined which is not a string.
