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="result" class="one two"></div>
Element.prototype.hasClass1 = function ( className )
{
return this.getAttribute( 'class' ).split( ' ' ).indexOf( className ) > -1;
};
Element.prototype.hasClass2 = function ( className )
{
return this.className.split( ' ' ).indexOf( className ) > -1;
};
var result = document.getElementById( 'result' );
Ready to run.
