What is happening in Crockford's object creation technique?

Question

There are only 3 lines of code, and yet I\'m having trouble fully grasping this:

Object.create = function (o) {
    function F() {}
    F.prototype = o;
             


        

Answer 1

Your major misunderstanding here is that F has global scope. It is declared in the body of Object.create and consequently is only in scope within that method block.
