I am learning JavaScript from the book "The Good Parts" and on Page 33, the author has written this piece of code:

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

What does this represent in this function?

The object which is calling `method`. – Tushar Dec 08 '16 at 11:43
@Tushar can we use this in properties ? – Mahi Dec 08 '16 at 11:45
@Mahi Yes, we can use `this` for properties as well as methods. – Tushar Dec 08 '16 at 11:46
@Tushar how . ?? can i write `obj={pro:this}` ?? – Mahi Dec 08 '16 at 11:49
@Tushar then property value is always window object ?? – Mahi Dec 08 '16 at 11:55
@Mahi I misunderstood your question. We cannot use this like that, that'll throw syntax error. – Tushar Dec 08 '16 at 11:56
@Tushar i also thought like that . but i am getting no error . try this in console. `var obj={ 1:this }` – Mahi Dec 08 '16 at 12:01
