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 obj = Object.fromEntries( Array.from({length: 1000}, e => [String.fromCharCode(e), e] ) );
let obj2 = {};
for(let key in obj)
obj2[key] = {jsobj: obj[key]}
function getMember(o, name) {
let val = o[name]
if(val !== undefined && val.jsobj === obj[name])
return val
throw new Error('unimplemented !')
}
Ready to run.
