Best regexp alternative for Go. Benchmarks. Plots.
To answer these questions, I wrote a small benchmarking program that can be used to compare different regex engines in terms of speed and memory usage. If you want to test it yourself or evaluate the correctness of the used methods, here is the code.

regexp2 (1.10.0) - a feature-rich regexp engine for Go. It does not have runtime guarantees like the built-in regexp package, but is compatible with Perl5 and .NET;

A CGo-free port of the PCRE2 regular expression library
It's also very useful if you're writing an interpreter which intends to be compatible with something that already needs PCRE support. For example, goja (a JS interpreter) uses regexp2 to support JS's regexp syntax, since JS is not limited to re2.

Converting ECMA script regex to golang
Compare https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions/Cheatsheet with https://github.com/dlclark/regexp2 - maybe github.com/dlclark/regexp2 is (almost) what you need.
