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
let array = Array.from({length: 10000}, (_e, i) => i); // big number to prevents browser cache
let array2 = array.map( e => { return {obj: e} });
let array3 = new Array(array.length).fill( (i) => array[i] )
at = (array, idx) => {
let val = array2[idx];
if( val !== undefined && val.obj === array[idx])
return val
// we should make the lazy conversion here
// but that wouldn't be fair.
throw 'not implemented'
};
at2 = (array, idx) => {
return array2[idx] // if you already use one
};
function update(_array, _i) {
throw new Error('Not implemented !')
}
Ready to run.
