Like
performance.now()
but in nanoseconds.
Although the value is always in nanoseconds, the time resolution might be less precise. For example, in Node.js, it is 1ns, but in Firefox it is 1ms and in Chrome it is 0.1ms.
Example
import preciseNow from 'precise-now'
const start = preciseNow()
const end = preciseNow()
const duration = end - start
Install
npm install precise-now
This package works in both Node.js >=18.18.0 and browsers.
This is an ES module. It must be loaded using
an import or import() statement,
not require(). If TypeScript is used, it must be configured to
output ES modules,
not CommonJS.
API
