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
In this test, different ways to access the last element of an array are analyzed. The test checks the performance of accessing the last element of a large array with a fallback to null if the array is empty.
const nodes = Array.from({ length: 100000 }, () => Math.random());Ready to run.
| Test | Ops/sec | |
