Constructors and method chaining in JavaScript
- by Sethen Maleno
I am trying to make method chaining work in conjunction with my constructors, but I am not exactly sure how to go about it. Here is my code thus far:
function Points(one, two, three) {
this.one = one;
this.two = two;
this.three = three;
}
Points.prototype = {
add: function() {
return this.result = this.one + this.two + this.three;
},
multiply: function() {
return this.result * 30;
}
}
var some = new Points(1, 1, 1);
console.log(some.add().multiply());
I am trying to call the multiply method on the return value of the add method. I know there is something obvious that I am not doing, but I am just not sure what it is.
Any thoughts?
