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
<script>
var regex = /[-#$^*()+[\]{}|\\,.?\s]/g,
regex_instance = new RegExp('[-#$^*()+[\\]{}|\\\\,.?\\s]', 'g'),
string = 'foo,bar(baz)',
testInFunctionUsingClosureLiteral = function(string) {
return string.replace(regex, '\\$&');
};
</script>
Ready to run.
