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
Different methods for clearing the canvas.
<script>
var c = document.createElement('canvas');
c.width = c.height = 500;
var ctx = c.getContext('2d');
ctx.fillStyle = 'rgba(0,0,0,1)';
var angle = Math.PI/4;
</script>
Ready to run.
