Static properties of Class

[dmjpro]

Actually a function is treated as a Class in JavaScript.

function MyClass(){

}

MyClass.prop = 100;
var mc = new MyClass();

Why mc.prop returns undefined?

[Dormilich]

because prop is a member of the MyClass Function object not the MyClass object. when you call the constructor, it executes the function specifyed (MyClass()), this functions returns an empty object.
