[javascript] How do I measure the execution time of JavaScript code with callbacks?

I had same issue while moving from AWS to Azure

For express & aws, you can already use, existing time() and timeEnd()

For Azure, use this: https://github.com/manoharreddyporeddy/my-nodejs-notes/blob/master/performance_timers_helper_nodejs_azure_aws.js

These time() and timeEnd() use the existing hrtime() function, which give high-resolution real time.

Hope this helps.
