In addition with non-enumerable properties you can just monkey-patch `Array.prototype` with the `peek` or `last` method. I guess approach when some library forces some method to widely used, can be a good candidate for adding it to the spec (this how it was with `Function.prototype.bind`, e.g., although today monkey-patching is a bad practice of course). In addition, you can monkey-patch just `-1`, and other indexes, e.g. a gist from 5 years old, when a similar topic was proposed here: https://gist.github.com/DmitrySoshnikov/984921 Dmitry
