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
var keys = []
for (var i = 0; i < 1000000; i++) {
keys.push("foo-" + i)
}
var obj = {}
keys.forEach(function (key) { obj[key] = true })
var map = new Map()
keys.forEach(function (key) { map.set(key, true) })
keys = null
obj = null
map = null
Ready to run.
