Tests:
ES6 Class
class Point { constructor(x, y){ this.x = x; this.y = y; } } function add(p1, p2) { return new Point(p1.x + p2.x, p1.y + p2.y); } function sub(p1, p2) { return new Point(p1.x - p2.x, p1.y - p2.y); } var p1 = new Point(10, 10); var p2 = new Point(10, -10); var sum = add(p1, p2); var dif = sub(p1, p2);
Function Prototype
function Point(x, y){ this.x = x; this.y = y; } function add(p1, p2) { return new Point(p1.x + p2.x, p1.y + p2.y); } function sub(p1, p2) { return new Point(p1.x - p2.x, p1.y - p2.y); } var p1 = new Point(10, 10); var p2 = new Point(10, -10); var sum = add(p1, p2); var dif = sub(p1, p2);
Object Literal
function add(p1, p2) { return Point(p1.x + p2.x, p1.y + p2.y); } function sub(p1, p2) { return Point(p1.x - p2.x, p1.y - p2.y); } function Point(x, y){ return { x, y, } } var p1 = Point(10, 10); var p2 = Point(10, -10); var sum = add(p1, p2); var dif = sub(p1, p2);
