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 = "Test test test abc test ... ";
var strTest = [
str1,
str1 + str1 + str1 + str1 + str1,
'Test',
''
];
function replaceAll(str, search_str, rep_str) {
if (~str.indexOf(search_str)) {
var prev;
do {
prev = str;
} while ((str = str.replace(search_str, rep_str)) !== prev);
}
return str;
}
Ready to run.
