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
If for some reason you find yourself with some JavaScript in a string that you want to add, which is faster?
var theJSString = 'var somethingForTheLoopToDo=0;var longLoop=500;while(longLoop--){somethingForTheLoopToDo+=longLoop;}';
Ready to run.
