JavaScript is a god language. Changing Array.prototype is very much considered an antipattern, except in the case of shims, where it's really useful. JavaScript is reinventing itself, introducing a nice, traditional OOP facade with `class`, and making improvements to functional-ish programming with `let` (as opposed to `var`), arrow functions, and object and array destructuring. The DOM is still very much a "try to display something at all costs" mess that doesn't at all fail fast, but most of the things that you want to happen are indeed happening!
