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 arrayLength = 10000;
var comparator = function(item) {

for (var i = 0; i < arrayLength; ++i) {
array.push(i);
}
return array;
}
Array.prototype.removeIf1 = function(expression) {
var res = [];
for (var idx = 0; idx < this.length; idx++) {
var currentItem = this[idx];
if (!expression(currentItem)) {
res.push(currentItem);
}
}
return res;
};
Array.prototype.removeIf2 = function(callback) {
var i = 0;
while (i < this.length) {
if (callback(this[i])) {
this.splice(i, 1);
} else {

}
}
};
