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
Added test cases for when the variables being combined are not both strings (but when the result will be a string due to implicit conversion)
<script>
var str = '',
hello = 'Hello ',
world = 'World ',
two = '22222 ',
three = 33333;
</script>
Ready to run.
