Tests:

  • ES6 Class

     
    var p1 = new Point1(10, 10);
    var p2 = new Point1(10, -10);
    var sum = p1.add(p2);
    var dif = p1.sub(p2);

  • Function Prototype

     
    var p1 = new Point2(10, 10);
    var p2 = new Point2(10, -10);
    var sum = p1.add(p2);
    var dif = p1.sub(p2);

  • Object Literal

     
    var p1 = Point3(10, 10);
    var p2 = Point3(10, -10);
    var sum = p1.add(p2);
    var dif = p1.sub(p2);

  • Functional

     
    var p1 = {x:10, y:10};
    var p2 = {x:10, y:-10};
    var sum = add(p1, p2);
    var dif = sub(p1, p2);
