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
Testing if access through Array.indexOf or Object's in Operator is faster.
var arr = [
'that',
'is',
'some',
'nice',
'some',
'test',
'here',
]
var obj = {
'that' : null,
'is' : null,
'some' : null,
'nice' : null,
'test' : null,
'here' : null
}
Ready to run.
