Would love if there was another option between those two as well. I know lots of people love Lua but I find it different enough that using it as an embedded scripting language is annoying. IE, I'm not programming in it all the time, so things like 1-indexing of arrays never becomes feels natural and I make indexing mistakes. Other differences like arrays and dictionaries being the same type cause other context switches which I dislike. (and can cause super subtle bugs in JSON marshaling and unmarshaling if you aren't careful)

I would really love a fast, lightweight stripped down "C Flavored Syntax" dynamic language to use instead of JS or Lua but I haven't found either yet.
