Every programming language has it's warts. JavaScript is in a unique position in terms of the level of backwards compatibility it is required to maintain. It integrates some powerful features with it's lisp-y functional style and closures. It's implementation of prototypal inheritence isn't the greatest I've seen, but it's by far the most successful prototype based language and that is something I personally wouldn't mind seeing become more mainstream.

Despite thinking JavaScript itself has some really great qualities; I generally don't think Electron is a great solution for desktop applications. Executables are too large and slow compared to a good old fashioned native application.
