How to make object as array? This TypeScript library makes objects as Array like and iterable.

var objNames = Object.getOwnPropertyNames(Object.prototype), arrNames = Object.getOwnPropertyNames(Array.prototype), iterableNames = arrNames.filter(function (name) {
    return objNames.indexOf(name) === -1;
});
function attachIterable(value) {
    if (!Symbol || !Symbol.iterator) {
        return;
    }
    Object.defineProperty(value, Symbol.iterator, {
        writable: false,
        enumerable: false,
        configurable: false,
        value: function () {
            var context = this;
            return {
                next: function () {
                    if (context.length && this._index < context.length) {
                        return { value: context[this._index++], done: false };
                    }
                    else {
                        return { done: true };
                    }
                },
                _index: 0
            };
        }
    });

                while (value[index] !== undefined) {
                    index++;
                }
                Object.defineProperty(value, "length", {
                    value: index,
