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

Revision 3 of this benchmark created by Bob Fornal on February 11, 2015

Description

I moved the variable declaration into "Preparation code", since it is not actually being changed by the tests. This should provide "truer" results.

Preparation HTML

<script>
var x = "5555";
</script>

Test runner

Ready to run.

Testing in
Test		Ops/sec
parse	`var y = parseInt(x, 10);`	ready
plus	`var y = +x;`	ready
