February 19, 2023Writing a JavaScript compiler; Haskell or Rust?
TLDR; target an efficient runtime but use Haskell to compile your language. I wrote a basic Lisp compiler in Rust (outputs Rust code). If I had to do it over I'd use Haskell but still target Rust (or C/C++ etc). Using Rust for parsing Lisp and outputting itself was a PITA because (1) no GC which was an unnecessary burden (2) Haskell had way better facilities for exactly this use case. Nothing against Rust, I just used it for the wrong thing. More on reddit.com
