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
Determine whether or not prefacing a class-name with an element name achieves any performance boost with jQuery selectors.
Hypothesis: like in CSS, adding an element name to the class name will not provide any performance boost, because selectors are evaluated right-to-left. Also, pseudo-selectors are slow.
