“The Luau author is always on the official Lua mailing list, and it has twice as many stars, so it seems likely to win the long term popularity contest.”

Many of us would love a TypeScript analogy for Lua. There have been some attempts: Luau (5.2k, last week, https://luau.org/ , https://github.com/edubart/nelua-lang ) Nelua (2.3k, 8 months ago, https://nelua.io/ , https://github.com/luau-lang/luau ) Terra (2.9k, 3 days ago, https://terralang.org/ , https://github.com/terralang/terra ) Teal (2.7k, 2 days ago, https://teal-language.org/ , https://github.com/teal-language/tl ) The Luau author is always on the official Lua mailing list, and it has twice as many stars, so it seems likely to win the long term popularity contest.
