If you're willing to exclude D because it "lacks momentum", Go because you'd "like to avoid it", and Rust because it's "too unfamiliar", then you're really out of options. I don't think there exist any other performant, popular, compiled languages that are similar to Javascript; all of them fail one of your criteria or another: - Haskell: very fast but probably more "unfamiliar" to you than Rust - Common Lisp: fast, very stable, easier than Haskell (semantics similar to Python/Javascript) but definitely not mainstream - FORTH: very fast but memory-unsafe and semantically+syntactically almost polar opposite of most popular languages
