I have a pretty decent experience in lua, js, python, perl and a few in other scripting languages, and personally wouldn't just throw js away in general. Yes, it is a legacy freak, but some latest parts of it are at least worth adopting in other languages. To name a few, constructing objects ({a, ...b, c:[...d, e]}), destructuring, arrow functions conciseness, proxies, default arguments. This helps much in scripting and libraries for scripting. Also I find separate objects and arrays being a better approach than just lua-tables. I like lua, really, but some parts of it... you have to struggle with constantly. Select and "..." sematics in general, meta restrictions, a bloaty syntax.

Imo, the next language with a little stricter typing than both js and lua, which takes best parts of these and gets rid of bad practices, and with a typed version in mind, will be a big win for everyone.

I upvoted this, although I disagree about tables vs. separate objects and arrays. If you were to say separate maps and a specialized array type, I would be more inclined to your point of view! Not sold completely, mind you.

In either case, it's a productive disagreement. I agree that Lua isn't a perfected language; merely a very, very good one.

From your list, I would takeaway default arguments as the first thing to bring over to this hypothetical successor language. Arrow functions could be avoided by the simple expedient of renaming the keyword `function` to simply `fn`.

What are proxies for?
