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
Measuring the performance implications of a try/catch block used with loops.
function foo() {
for(var i = 0; i < 500; i++){
var n = 1;
}
}
function bar() {
for(var i = 0; i < 500; i++){
var n = 1;
}
}
function zap() {
for(var i = 0; i < 500; i++){
var n = 1;
}
(0)();
}
function abc() {
for(var i = 0; i < 500; i++){
var n = 1;
}
}
function def() {
for(var i = 0; i < 500; i++){
var n = 1;
}
(0)();
}
function tryWrap(closure, catchCB) {
try {closure();}catch(e){if(catchCB){catchCB(e);}}
}
