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
Expando on the node versus an object in a WeakMap
<div id="node1">Node 1</div>
<div id="node2">Node 2</div>
const
node1 = document.getElementById('node1'),
node2 = document.getElementById('node2'),
map = new WeakMap(),
value = [];
node1._data = {};
map.set(node2, {});
Ready to run.
