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
var str1 = "foo.bar[car]",
str2 = "foobarcar"
re = /^[^[.]+$/,
re2= /[[.]/;
function check1(value) {
return re.test(value);
}
function check2(value) {
return value.indexOf('.') < 0 && value.indexOf('[') < 0;
}
function check3(value) {
return !re2.test(value);
}
Ready to run.
