Constructor for callable object in JavaScript [duplicate]

Answer 1

If you want the CallablePoint() constructor to return an object of type CallablePoint, then you can do something like this where the CallablePoint object contains a point as a property of the object, but remains a CallablePoint object:

function CallablePoint(x, y) {
    this.point = {};
    this.point.x = x
    this.point.y = y
}

or, if what you're really trying to do is to make a function that returns you an object of CallablePoint, then you can create a factor function:

function CallablePoint(x, y) {
    this.point = {};
    this.point.x = x
    this.point.y = y
}

function makeCallablePoint(x, y) {
   return new CallablePoint(x,y);
}
