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="canvas1" width="500" height="500"></canvas>
<script>
var can = document.getElementById('canvas1');
var ctx = can.getContext('2d');
var can2 = document.createElement('canvas');
can2.width = 150;
can2.height = 150;
var ctx2 = can2.getContext('2d');
ctx.clearRect(0,0, can.width, can.height);
ctx2.clearRect(0,0, can2.width, can2.height);
ctx2.beginPath();
ctx2.strokeStyle = 'red';
ctx2.lineWidth = 4;
ctx2.moveTo(10,10);
ctx2.lineTo(10,30);
ctx2.lineTo(30,30);
ctx2.lineTo(40,70);
ctx2.quadraticCurveTo(72,43,22,12);
ctx2.quadraticCurveTo(12,43,12,102);
