it returns same type of object, here's trivial illustration demonstrates technique:

var counter = function(){ this.val = 0; }; counter.prototype.increment = function(){ ++this.val; homecoming this; }; counter.prototype.decrement = function(){ --this.val; homecoming this; }; counter.prototype.log = function(){ console.log(this.val); homecoming this; }; var o = new counter(); o.increment().increment().decrement().log().increment().log();
