fs.symlinkSync(target, path[, type]) Synchronous symlink(2). Returns undefined.

repl.start([options]) Returns and starts a REPLServer instance, that inherits from Readline Interface. Accepts an "options" Object that takes the following values: prompt - the prompt and stream for all I/O. Defaults to > . input - the readable stream to listen to. Defaults to process.stdin. output - the writable stream to write readline data to. Defaults to process.stdout. terminal - pass true if the stream should be treated like a TTY, and have ANSI/VT100 escape codes written to it

assert.fail(actual, expected, message, operator) Throws an AssertionError. If message is falsy, the error message is set as the values of actual and expected separated by the provided operator. Otherwise, the error message is the value of message. const assert = require('assert'); assert.fail(1, 2, undefined, '>'); // AssertionError: 1 > 2 assert.fail(1, 2, 'whoops', '>'); // AssertionError: whoops

ref() If a timer was previously unref()d, then ref() can be called to explicitly request the timer hold the program open. If the timer is already refd calling ref again will have no effect. Returns the timer.

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. Streams are readable, writable, or both. All streams are instances of EventEmitter. You can load the Stream base classes by doing require('stream'). There are base classes provided for Readable streams, Writable streams, Duplex streams, and Transform streams. This document is split up into 3 sections: The first section e

worker.id <Number> Each new worker is given its own unique id, this id is stored in the id. While a worker is alive, this is the key that indexes it in cluster.workers

Class: https.Server This class is a subclass of tls.Server and emits events same as http.Server. See http.Server for more information.

process.getgroups() Note: this function is only available on POSIX platforms (i.e. not Windows, Android) Returns an array with the supplementary group IDs. POSIX leaves it unspecified if the effective group ID is included but Node.js ensures it always is.

emitter.addListener(eventName, listener) Alias for emitter.on(eventName, listener).
