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

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.equal(actual, expected[, message]) Tests shallow, coercive equality between the actual and expected parameters using the equal comparison operator ( == ). const assert = require('assert'); assert.equal(1, 1); // OK, 1 == 1 assert.equal(1, '1'); // OK, 1 == '1' assert.equal(1, 2); // AssertionError: 1 == 2 assert.equal({a: {b: 1}}, {a: {b: 1}}); //AssertionError: { a: { b: 1 } } == { a: { b: 1 } } If the values are not equal, an AssertionError is thrown with a message property

fs.accessSync(path[, mode]) Synchronous version of fs.access(). This throws if any accessibility checks fail, and does nothing otherwise.

global {Object} The global namespace object. In browsers, the top-level scope is the global scope. That means that in browsers if you're in the global scope var something will define a global variable. In Node.js this is different. The top-level scope is not the global scope; var something inside an Node.js module will be local to that module.

Event: 'timeout' Emitted if the socket times out from inactivity. This is only to notify that the socket has been idle. The user must manually close the connection. See also: socket.setTimeout()

fs.linkSync(srcpath, dstpath) Synchronous link(2). Returns undefined.

Event: 'continue' function () { } Emitted when the server sends a '100 Continue' HTTP response, usually because the request contained 'Expect: 100-continue'. This is an instruction that the client should send the request body.

fs.read(fd, buffer, offset, length, position, callback) Read data from the file specified by fd. buffer is the buffer that the data will be written to. offset is the offset in the buffer to start writing at. length is an integer specifying the number of bytes to read. position is an integer specifying where to begin reading from in the file. If position is null, data will be read from the current file position. The callback is given the three arguments, (err, bytesRead, buffer).

tlsSocket.getCipher() Returns an object representing the cipher name and the SSL/TLS protocol version that first defined the cipher. Example: { name: 'AES256-SHA', version: 'TLSv1/SSLv3' } See SSL_CIPHER_get_name() and SSL_CIPHER_get_version() in https://www.openssl.org/docs/manmaster/ssl/SSL_CIPHER_get_name.html for more information.
