Is there any way to get current time in nanoseconds using JavaScript?

Question

So, I know I can get current time in milliseconds using JavaScript. But, is it possible to get the current time in nanoseconds instead?

Answer 1

In Server side environments like Node.js you can use the following function to get time in nanosecond

function getNanoSecTime() {
  var hrTime = process.hrtime();
  return hrTime[0] * 1000000000 + hrTime[1];
}

Also get micro seconds in a similar way as well:

function getMicSecTime() {
  var hrTime = process.hrtime();
  return hrTime[0] * 1000000 + parseInt(hrTime[1] / 1000);
}
