Javascript - The new method -

if break down me, can understand it, i'd greatful. know it's used create new object apply method.

function.prototype.new = function () {     var args = arguments;     var constructor = this;      function fake() {         constructor.apply(this, args)     };     fake.prototype = constructor.prototype;     return new fake; }; 

basically, function new used inherit prototype methods on newly created object 1 on being called.

// new function defined on function prototype so, // can called directly function function.prototype.new = function () {     // caching arguments array-like object     var args = arguments;      // inside new() refers function on `new` called     var constructor = this;      // fake constructor function/class     function fake() {         // calling function passing context , arguments         constructor.apply(this, args)     };      // adding prototype members of function on new called     // on new fake class     fake.prototype = constructor.prototype;      // retun new instance of fake class     // returning prototypes here     return new fake; };
