I'm not a fan of Go, but I have to admit that benchmark doesn't make any sense. If you use tail calls in a language that doesn't support TCO, then of course you'll get bad results.

I guess its easier to just throw in some numbers than compare idiomatic implementations and then discuss tradeoffs with some nuance.

Even if its just a language teaser, I'd still add a note on TCO to avoid misleading people though.

Yes, using WASM and Go in an contrived example and not mentioning tinyGo is not very honest.

Do you have reason to believe that tinyGo would do better on that particular benchmark?

Based on the name, I’d imagine part of TinyGo’s raison d`être would be a smaller binary size. Plus, seems optimized for speed rather than speed-of-compiler

That's not how you'd implement it in rust either. It's a pretty bad benchmark. From my experience, I'd guess it's lack of tail recursion and the switch statement. That one can be slow in Go.

It is however a good teaser for Moonbit.
