FAQ

How does it compare to Emscripten

Emscripten is able to compile the libc where Holyc won't.

You can easily reproduce this benchmark by following C_to_wasm.

hello.c:

int main() {
  return 0;
}

Emscripten:

file	size (bytes)
hello.wasm	21856
hello.js (loader)	99710

Holyc:

file	size (bytes)
hello.wasm	78
hello.js (loader)	unknown currently (see here for a hint)
