It’s nearly all in Zig. The parser, lexer, interpreter, process execution and builtin commands are all implemented in Zig. There’s a JS wrapper that extends Promise but JS doesn’t do much else. The performance of the interpreter probably isn’t as good as bash, but the builtin commands should be competitive with GNU coreutils. We have spent a lot of time optimizing our node:fs implementation and this code is implemented similarly. We expect most scripts to be simple one-liners since you can use JS for anything more complicated.
