JavaScript is so much more widely used for so many applications that it’s hard to justify LuaJIT, even if it is faster. They’re both much faster than most scripting languages like Python and Ruby.
If JavaScript really isn’t fast enough, then I think you should be thinking about something like Go or Rust instead.
LuaJIT is an incredible piece of technology, but in this performance tier JavaScript has won out due to sheer ubiquity and the size of its ecosystem.
Edit: I never said slow was okay. I’m not advocating for slow, I’m just saying that the target audience for RJIT is developers who are already using Ruby. For significantly better speed, you probably want to look elsewhere.
