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
function obj() {
var x = {};
for (var i = 0; i < 100; i++)
x['v' + i] = i;
return x;
}
function iterate(stuff) {
for (var x in stuff) {
var y = stuff[x];
}
}
function forEachIterate(stuff) {
Object.keys(stuff).forEach(function(x) {
var y = stuff[x];
});
}
var unfrozen = obj();
var frozen = obj();
Object.freeze(frozen);
Ready to run.
