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 arr = []
let i = 0
while (i < 10_000) {
arr.push({ obj: i })
i++;
}Ready to run.
| Test | Ops/sec | |
|---|---|---|
| a = []; | | ready |
| a.length = 0; | | ready |
| a.splice(0, a.length) // 97% slower | | ready |
| while pop | | ready |
