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
Investigating a means of replacing the try catch block with a custom solution for performance intensive operations in a loop.
function tryCatch (tryFn, catchFn) {
try {
tryFn()
} catch (e) {
catchFn(e)
}
}
function tryError (fn) {
try {
fn()
} catch (e) {
return e
}
}
function cachedTry () {
if (Math.random() > 0.9) {
throw new Error
}
}
function cachedCatch (e) {
console.log(e)
}
Ready to run.
