I used to like Lua a lot and now I don’t. I think anyone intending to add a scripting language to their game/engine should seriously consider using Javascript instead.

Javascript is used all over the web. It’s only going to end up getting used more and more. Google, Mozilla and Microsoft are all working to make it faster and faster.

Ultimately if we have to teach people a scripting language, lets teach them a language that will serve them in the future. Sure the jump from Lua to Javascript isn’t that great, but if you skip Lua there’s no need to make a jump at all.

I'm not talking about memory or complexity, I'm talking about verbosity. don't get me wrong, I'm not advocating switching to APL just so your source files will be smaller, I just think that things you write all the time (block delimitation) should be quick to write. this is why I really dislike Java (at least pre-Java 8, modern Java is tolerable in comparison): there's just too much boring boilerplate.
