jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
.replace only replaces first instance of search string. to replace all we can either use a greedy regex or split (split on search and join on replacement). Which is faster tho?
var str = 'some code with "replacements"';
var replacement = '\\"';
var search = '"';
var regex = new RegExp(search, 'g');
Ready to run.
