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
Test different access method to an object property
<script>
obj = {
_x: 0
}
function Proto() {
this.x = 0
}
function ProtoDefineInner() {
var _x = 0
Object.defineProperty(this, 'x', {
get: function () { return _x },
set: function (val) { _x = val }
})
}
</script>
Ready to run.
