JavaScript prototyping shortest explanation

Posted by admin - 22/07/10 at 09:07:22 am

 
// Without prototyping
 
function Foo() {
    this.do = function(){
    }
}
 
var f1 = new Foo()
var f2 = new Foo()
f1.do == f2.do // FALSE
 
// With prototyping:
 
function Bar(){
}
 
Bar.prototype.do = function(){
}
 
var b1 = new Bar()
var b2 = new Bar()
b1.do == b2.do // TRUE
