> I am also wondering if Meta still uses PHP or Hack
Meta’s WWW codebase is its oldest, and still written in Hacklang. Lots of internal tooling is also written in Hack.
I wouldn’t be surprised if there are more committed lines of Hacklang than any other language (although, a good chunk of that is codegen, vs other core languages where codegen is part of the build process).
