process.hrtime() Returns the current high-resolution real time in a [seconds, nanoseconds] tuple Array. It is relative to an arbitrary time in the past. It is not related to the time of day and therefore not subject to clock drift. The primary use is for measuring performance between intervals. You may pass in the result of a previous call to process.hrtime() to get a diff reading, useful for benchmarks and measuring intervals: var time = process.hrtime(); // [ 1800216, 25 ] setTimeout(() =&

clearImmediate(immediateObject) Stops an immediateObject, as created by setImmediate, from triggering.

Stability: 2 - Stable A stream is an abstract interface implemented by various objects in Node.js. For example a request to an HTTP server is a stream, as is process.stdout.
