What does HackerNews think of regex-benchmark?

It obviously depends on how you've implemented the feature, but there are a lot of cpmparitive benchmarks if you bother to put "go vs JS Performance benchmark" into the search bar and press enter. The language itself doesn't make code performance however, so you'll have good and bad implementations in any language you go with.

I.e. specifically regex, which is highly relevant in searching through strings: https://github.com/mariomka/regex-benchmark

And the always interesting techempower Project, which leaves the implementation to participants of each round. https://www.techempower.com/benchmarks/#section=data-r21&tes...

Choose whatever category you wish there, js is faster then go in almost all categories there.

Even though I said it before, I'm going to repeat myself as I expect you to ignore my previous message: the language doesn't make any implementation fast or slow. You can have a well performing search engine in go and JS. The performance difference will most likely not be caused by the language with these two choices. And the same will apply with C/Rust. The language won't make the engine performant and creating a maximally performant search engine is hard. But a theoretically perfect implementation would likely be fastest in C/Rust, followed by the usual suspects such as Go/Java/C#/JS and finally ending with all other interpreted languages such as ruby and python

Interesting. Looking at this repo, they have

Rust -> Ruby -> Java -> Golang

Though it appears the numbers are two years old or so, and only for 3 specific regexes.

It is a matter of personal preference.

I find that regular expressions and text-wrangling tasks are faster and easier in Perl than in other programming languages due to its accessible syntax and regular expression engine speed.

This article shows the regular expression syntax in several popular programming languages: https://cs.lmu.edu/~ray/notes/regex/

This GitHub repo gives some regex performance test benchmarks: https://github.com/mariomka/regex-benchmark Perl is pretty fast among the scripting languages that were benchmarked.

If you are familiar with C / C++, then learning Perl is relatively fast and easy: https://perldoc.perl.org/perlintro
