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
This test is motivated by the use of duck typing in the current underscore.js implementation for _.isType() functions.
<script>
var obj0 = new Date(),
obj1 = {
a: 5,
b: 7
},
obj2 = new Date(2009, 0, 5),
obj3 = 8;
</script>
Ready to run.
