/**
* The `tty` module provides the `tty.ReadStream` and `tty.WriteStream` classes.
* In most cases, it will not be necessary or possible to use this module directly.
* However, it can be accessed using:
*
* ```js
* const tty = require('tty');
* ```
*
* When Node.js detects that it is being run with a text terminal ("TTY")
* attached, `process.stdin` will, by default, be initialized as an instance of`tty.ReadStream` and both `process.stdout` and `process.stderr` will, by
* default, be instances of `tty.WriteStream`. The preferred method of determining
* whether Node.js is being run within a TTY context is to check that the value of
* the `process.stdout.isTTY` property is `true`:
*
* ```console
* $ node -p -e "Boolean(process.stdout.isTTY)"
* true
* $ node -p -e "Boolean(process.stdout.isTTY)" | cat
* false
* ```
*
* In most cases, there should be little to no reason for an application to
* manually create instances of the `tty.ReadStream` and `tty.WriteStream`classes.
* @see [source](https://github.com/nodejs/node/blob/v18.0.0/lib/tty.js)
