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
<canvas id="a" width="256" height="256"></canvas>
<canvas id="b" width="256" height="256"></canvas>
<script>
var c1 = document.getElementById("a");
var ctx = c1.getContext("2d");
var c2 = document.getElementById("b");
var ctx2 = c2.getContext("2d");
ctx2.fillStyle = '#000';
ctx2.fillRect( 0, 0, 300, 300 );
</script>
Ready to run.
