Show HN: wcwidth-o1 – Find Unicode text cell width in no time for JavaScript/TS
github.comI ported Markus Kuhn’s wcwidth to TypeScript and optimized it with bitset lookups for O(1) performance. It now covers the full Unicode 15.1 combining ranges.

Feedback welcome!
I was about to say you could figure this kind of thing out with Intl.Segmenter but then saw it was a different problem. Nice.
Nice
