 /**
  * The `fs` module enables interacting with the file system in a
  * way modeled on standard POSIX functions.
  *
  * To use the promise-based APIs:
  *
  * ```js
  * import * as fs from 'fs/promises';
  * ```
  *
  * To use the callback and sync APIs:
  *
  * ```js
  * import * as fs from 'fs';
  * ```
  *
  * All file system operations have synchronous, callback, and promise-based
  * forms, and are accessible using both CommonJS syntax and ES6 Modules (ESM).

      * Asynchronous [`stat(2)`](http://man7.org/linux/man-pages/man2/stat.2.html). The callback gets two arguments `(err, stats)` where`stats` is an `fs.Stats` object.
      *
      * In case of an error, the `err.code` will be one of `Common System Errors`.
      *
      * Using `fs.stat()` to check for the existence of a file before calling`fs.open()`, `fs.readFile()` or `fs.writeFile()` is not recommended.
      * Instead, user code should open/read/write the file directly and handle the
      * error raised if the file is not available.
      *
      * To check if a file exists without manipulating it afterwards, {@link access} is recommended.
      *
      * For example, given the following directory structure:
      *
      * ```text
      * - txtDir
      * -- file.txt
      * - app.js
      * ```
      *
      * The next program will check for the stats of the given paths:
      *
      * ```js
      * import { stat } from 'fs';
      *
      * const pathsToCheck = ['./txtDir', './txtDir/file.txt'];
      *
      * for (let i = 0; i < pathsToCheck.length; i++) {
      *   stat(pathsToCheck[i], (err, stats) => {
      *     console.log(stats.isDirectory());
      *     console.log(stats);
      *   });
      * }
      * ```
      *
      * The resulting output will resemble:
      *
      * ```console
      * true

      *   stream.close(); // This may not close the stream.
      *   // Artificially marking end-of-stream, as if the underlying resource had
      *   // indicated end-of-file by itself, allows the stream to close.
      *   // This does not cancel pending read operations, and if there is such an
      *   // operation, the process may still not be able to exit successfully
      *   // until it finishes.

      * behavior), on `'error'` or `'end'` the file descriptor will be closed
