Excuse my multiple comments, just trying to understand this better since I’m very intrigued by your library.

What does the JS “if x != x” check do? I don’t see the equivalent in the golang example?

From the concurrent prime sieve example?

That's just something I copy and pasted from the documentation for the benchmark package I used. Allegedly, it is to prevent "certain compiler optimisations", which is something I'm familiar with when it comes to benchmarking Go code, for example.

I lack specific knowledge as to whether it's actually necessary, sorry :)

Ah, gotcha!

I thought maybe it was something to do with concurrency, and somehow x is affected by a race condition there.
