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);
Array
function Point(x, y) { return [x,y]; } function Point_add(p0, p1) { return [p0[0] + p1[0], p0[1] + p1[1]]; } function Point_sub(p0, p1) { return [p0[0] - p1[0], p0[1] - p1[1]]; } var p1 = Point(10, 10); var p2 = Point(10, -10); var sum = Point_add(p1, p2); var dif = Point_sub(p1, p2);
Array w/destr
function Point(x, y) { return [x,y]; } function Point_add([x0,y0], [x1,y1]) { return [x0 + x1, y0 + y1]; } function Point_sub([x0,y0], [x1,y1]) { return [x0 - x1, y0 - y1]; } var p1 = Point(10, 10); var p2 = Point(10, -10); var sum = Point_add(p1, p2); var dif = Point_sub(p1, p2);
