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

Setup

const objectsA = new Array(10000).fill({a:1});
const objectsB = new Array(10000).fill({a:1});

Test runner

Ready to run.

Spread

Testing in
Test	Ops/sec
Spread	`const spread = [...objectsA, ...objectsB]; const max = Math.max(...spread.map(object => object.a + 1));`	ready
Looping (Greedy Algorithm)	`let max = -Infinity; for (let array of [objectsA, objectsB]) { for (let object of array) { max = Math.max(max, object.a + 1); } }`	ready

const spread = [...objectsA, ...objectsB];
const max = Math.max(...spread.map(object => object.a + 1));

ready

Looping (Greedy Algorithm)

let max = -Infinity;
for (let array of [objectsA, objectsB]) {
	for (let object of array) {
		max = Math.max(max, object.a + 1);
	}
