alt Hacker News> assuming that URLPattern is performant
Whose implementation, specifically? I don't think as specified URLPattern has any inherent performance drawbacks compared to the alternatives, but it seems like V8/NodeJS/Deno definitely didn't thought closely and/or clearly about performance when they did theirs.
All three of those use the same implementation. I would hope that this will be improved over time, but it's not a guarantee by any stretch of the imagination.
