Hi, glad to see someone try compare how different compilers produce wasm's binary.
But I should be mentioned in AS version you use number type which just alias of f64 instead int32 as in C version. So AS version should looks like:

function fibonacci(i: i32): i32 { // or i64
  if (i < 0) return -1
  else if (i == 0) return 0
  else if (i == 1) return 1
  else return fibonacci(i - 1) + fibonacci(i - 2)
}

Another issue is AS doesn't use optimization at all in your build command. So much better is:

"asbuild": "asc src/ts/main.ts -b src/ts/a.out.wasm -t src/ts/a.out.wat --validate --measure -O3"

Thanks!
