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