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
Investigating a means of replacing the try catch block with a custom solution for performance intensive operations.
<script>
var callback = null;
window.onerror = function(msg, file, line){
var error = new Error(msg, file, line);
if(callback){
callback(error);
callback = null;
}
return true;
};
function tryCatch(fn, fail){
callback = fail;
fn();
callback = null;
}
function test(){
var n = 1;
}
function error(){
return null;
}
</script>
Ready to run.
