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
<div class="fooClass" data-attr="fooAttr"></div>
<div class="fooClass"></div>
<div class="fooClass"></div>
function getAllElementsWithAttribute(attribute)
{
var matchingElements = [];
var allElements = document.getElementsByTagName('*');
for (var i = 0, n = allElements.length; i < n; i++)
{
if (allElements[i].getAttribute(attribute) !== null)
{
// Element exists with attribute. Add to array.
matchingElements.push(allElements[i]);
}
}
return matchingElements;
}
Ready to run.
