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 testStr = 'UInt32';
const lookupTable = {'UInt8': true,'UInt16': true,'UInt32': true,'Int8': true,'Int16': true,'Int32': true};
const lookupSet = new Set(['UInt8','UInt16','UInt32','Int8','Int16','Int32']);
Ready to run.
Test | Ops/sec | |

lookupTable[testStr] |

parseInt(testStr.split('Int')[1]) > 32 |
