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
idea is to expand test having other elements with similar name. find out if prefiletring helps if it is a minority 10% of elements wonder if missing teardown.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script>
var $body = $('body'),
$div = $('<div class="products"/>', {
innerHTML: 'products'
}),
$span = $('<span class="productNot"/>', {
innerHTML: 'other'
});
for (var i = 0; i < 500; i++) {
$body.append($div);
}
for (var i = 0; i < 4500; i++) {
$body.append($span);
}
</script>
Ready to run.
