Investigating a means of replacing the try catch block with a custom solution for performance intensive operations.

Preparation HTML

<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;        
}
function nestedFunction() {
    var n = 1;
}
</script>
