If you have an object with certain methods, if each method returns an object with methods, you can simply call a method from the object returned.

var obj = {   // every method returns obj---------v

    first: function() { alert('first');   return obj; },

    second: function() { alert('second'); return obj; },

    third: function() { alert('third');   return obj; }

}



obj.first().second().third();
