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
Compares rendering an alternating pinstripe pattern with two approaches:
<canvas id="c" width="640" height="480"></canvas>
<script>
var canvas = document.getElementById('c');
var context = canvas.getContext('2d');
var GAP = 10;
var COLOR1 = 'red';
var COLOR2 = 'blue';
var STRIPES = 20;
</script>
context.clearRect(0, 0, canvas.width, canvas.height);
Ready to run.
