Array Dot Notation JS Example

ArrayDotNotation_Habitable.js

'use strict';
const ogp = Object.getPrototypeOf;
const osp = Object.setPrototypeOf;

const MyArrayConstructor = function() {};
osp(MyArrayConstructor.prototype, new Array);

class MyArray extends MyArrayConstructor {
    constructor(...args) {
