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 the performance of various ways of converting hex strings to numbers:
+str
)Number
functionparseInt
with a radix<div id="theDiv" data-val="0x20"></div>
<script>
var str = document.getElementById("theDiv").getAttribute("data-val");
var n;
</script>
Ready to run.
