Regex doesn't feature in this kind of library, at least not in mine. It's a token by token comparison/weighing, for which regular expressions are unsuitable. Mine looks at string prefixes and does a Levenshtein comparison on the results, and I think OP's project does that too.

The techempower benchmarks seem geared towards http backend server frameworks. There's only one Javascript framework that scores well, "just-js", but that's a bit low-level for a framework. I don't think it says much about text search performance.

Not ignoring that, but I think it's half true (you can't have a well performing app in native Python, basically, but a bad implementation will also cost a lot of performance). JS is fast enough for most tasks, that's true.
