Answer 1

You can create your own something like

 if (!Object.defineProperty) {
            Object.defineProperty = function (obj, prop, descriptor) {
                if (arguments.length < 3) { // all arguments required
                    throw new TypeError("Arguments not optional");
                }

                prop += ""; // convert prop to string
                ...
