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
const envsArr = new Array(1000).map(i => date.now()).map(n => ({name: n + '', stage: n % 2 === 0 ? 'alpha' : 'beta'}));
const envsMap = envsArr.reduce((acc, env) => {
acc[env.name] = {stage: env.stage};
return acc;
}, {});
const createNameForEnv = (input) => `${input.name}-${input.stage}`;
const createEnvs = (envs) => envs.forEach(env => createNameForEnv(env));
const createNameForEnv2 = (envName, env) => `${envName}-${env.stage}`;
const createEnvs2 = (envs) => Object.keys(envs).forEach(key => createNameForEnv2(key, envs[key]));
Ready to run.
