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

Performance of Array vs. Object (v13)

Revision 13 of this benchmark created by Marcin on December 5, 2012

Description

After seeing http://jsperf.com/javascript-associative-vs-non-associative-arrays, I thought the test could be improved.

Setup

var arr = [9, 9],
        obj = {
        one: 9,
        two: 9
        },
        one = 9,
        two = 9;

Test runner

Ready to run.

Testing in
Test		Ops/sec
Array Performance	`var sum = arr[0] + arr[1]`	ready
Object Performance	`var sum = obj.one + obj.two`	ready
Variable performance	`var sum = one + two`	ready
Primitive performance	`var sum = 9 + 9`	ready
