Why don't they do codegen at build time in Hack?
1 comments

Hack does JIT compilation.

Even otherwise, at the scale the company operates it's much better to run codegen once at commit time rather than recreate the entire codebase on every deploy (several times a day) which would take forever.

Why don't they do the same in other languages, then?
