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
function doTpl (x) {
// do nothing
}
function doExpr (x) {
// do nothing
}
var tpl = 'Hello {foo.bar}';
var notpl = 'Hello world';
function usingIndexOf (s) {
if (s.indexOf('{') < 0) {
doExpr(s);
} else {
doTpl(s);
}
}
var regex = /\{/;
function usingRegExp (s) {
if (regex.test(s)) {
doExpr(s);
} else {
doTpl(s);
}
}
Ready to run.
