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

Achieve microsecond accuracy in most browsers using:

window.performance.now()
