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
Used correctly (i.e., creating the object before the lookup), anonymous objects can be much, much faster than switch statements.
var key = 'a',
values = {
"a": "aaa",
"b": "bbb",
"c": "ccc",
"d": "ddd",
"e": "eee"
};
Ready to run.
