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
For cases in which you want an attribute that works like a flag.
<input id="inputSame" type="text" value="The quick brown fox jumps over the lazy dog">
<input id="inputDifferent" type="text" value="The quick brown fox jumps over the lazy dog">
<script>
var inputSame = document.getElementById("inputSame");
var inputDifferent = document.getElementById("inputDifferent");
var stringSame = "same";
var stringDifferent = "different";
var removeThenSet = function(input) {
input.removeAttribute("aria-label");
input.setAttribute("aria-label", stringSame);
}
var setOnly = function(input) {
input.setAttribute("aria-label", stringSame);
}
var setIfDifferent = function(input, logSomething) {
var value = input.getAttribute("aria-label");
if (value !== stringSame) {
input.setAttribute("aria-label", stringSame);
}
}
</script>Ready to run.
