Yep. This was the biggest thing that turned me off Go. I ported the same little program (some text based operational transform code) to a bunch of languages - JS (+ typescript), C, rust, Go, python, etc. Then compared the experience. How were they to use? How long did the programs end up being? How fast did they run?

I did C and typescript first. At the time, my C implementation ran about 20x faster than typescript. But the typescript code was only 2/3rds as many lines and much easier to code up. (JS & TS have gotten much faster since then thanks to improvements in V8).

Rust was the best of all worlds - the code was small, simple and easy to code up like typescript. And it ran just as fast as C. Go was the worst - it was annoying to program (due to a lack of enums). It was horribly verbose. And it still ran slower than rust and C at runtime.

I understand why Go exists. But I can't think of any reason I'd ever use it.
