Those are all very important comparisons (and I would add that both Lua and JS got the global by default thing wrong0. I would note that ES6 requires proper tail calls and that trampolining can accomplish tail call elimination (tail call elimination is different than proper tail calls).

The major issue to me is time. I know quite a few languages, but have only mastered a couple. JS is everywhere and the browser makes sure this will be the case for a long time.

The issue is that these advantages do not outweigh the ubiquitous nature of JavaScript. If I already need to learn all of those JS quirks, why learn Lua too?
