Is console.time() safe in node.js?

Question

I have a little snippet of node.js code in front of me that looks like this:

console.time(\"queryTime\");
doAsyncIOBoundThing(function(err, results) {
    consol         


        

Answer 1

Wouldn't this simple code work?

var labelWithTime = "label " + Date.now();
console.time(labelWithTime);
// Do something
console.timeEnd(labelWithTime);

Answer 2

Just use unique labels and it will be safe. That's why you use a label, to uniquely identify the start time.

As long as you don't accidentally use a label twice everything will work exactly as intended. Also note that node has usually only one thread of execution.

Answer 3

Consider new NodeJS features as it has evolved too. Please look into:

process.hrtime() & NodeJS's other performance API hooks:
