ES6 Class
class BaseClass { constructor() {} } class Point extends BaseClass { constructor(x, y) { super(); 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 Point1 = Point; var p1 = new Point1(10, 10); var p2 = new Point1(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Function Prototype
function BaseConstructor() {} function Point2(x, y) { this.x = x; this.y = y; } Point2.prototype.add = function(point) { return new Point2(this.x + point.x, this.y + point.y); } Point2.prototype.sub = function(point) { return new Point2(this.x - point.x, this.y - point.y); } Object.setPrototypeOf(Object.setPrototypeOf(Point2, BaseConstructor).prototype, BaseConstructor.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
function PointX(x, y) { return {} } function Point3(x, y) { return { ...PointX(x, y), x, y, add: (point) => Point3(x + point.x, y + point.y), sub: (point) => Point3(x - point.x, y - point.y) } } var p1 = new Point3(10, 10); var p2 = new Point3(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
