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
This is just a test I did to see which is faster, the JS version or the jQuery version. Both are Javascript based, but I just wanted to see whether jQuery got away with something when it comes down to performance and memory management
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<script>
// Setup collection
var collection = [];
for (var i = 0; i < 20000; i++) {
collection.push({
index: i,
data: 'Index element ' + i
});
}
</script>
Ready to run.
