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 id="test">
<p>some text</p>
<p>some other text</p>
<p>nothing</p>
</div>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
var $div = $('#test'),
withCheck = function(text) {
if ($div.children(':contains("' + text + '")') === 0) {
$div.empty();
}
$div.append('<p>' + text + '</p>');
},
withoutCheck = function(text) {
$div.empty().append('<p>' + text + '</p>');
};
</script>
Ready to run.
