In JavaScript, is there a way to inherit from the Number function?

Question

So I know I can do this...

Number.prototype.square = function () { return this * this }
 [Function]
4..square()
 16

Is there a way to inherit f

Answer 1

using Object.defineProperty allows you to have a little more control over the object.

Object.defineProperty(Number.prototype,'square',{value:function(){
 return this*this
},writable:false,enumerable:false});
//(5).square();

with your own lib it's the same...

Object.defineProperty(NumLib.prototype,'square',{value:function(){
 return this.whatever*this.whatever
},writable:false,enumerable:false});
