hi All,
I have question around Douglas Crockford "method" method.

Function.prototype.method = function (name, func) {
    this.prototype[name] = func;
    return this;
};
function azerizor(value) {
this.value=value;
}


azerizor.method('toString', function () {

    return this.value;
});
var me = new azerizor('salam').toString();

alert(me);

this is it. But here arises question regarding return this?
what does mean here return this? this method works without return this. I have read about that. so that one say that it is for chaining. But i didnt understand how can i use chaining using this "method" function. Thanks in advance for attention. I will wait your responses!

Chaining is calling one function after another on the same object. Returning the object is a way to accomplish that. It allows you to write.

anObject.method1().method2().method3();
