                 *
                 * The shell that executed Node.js should see the exit code as `1`.

                 * completed fully, including I/O operations to `process.stdout` and`process.stderr`.
                 *
                 * In most situations, it is not actually necessary to call `process.exit()`explicitly. The Node.js process will exit on its own _if there is no additional_

                 * tell the process which exit code to use when the process exits gracefully.
                 *
                 * For instance, the following example illustrates a _misuse_ of the`process.exit()` method that could lead to data printed to stdout being
                 * truncated and lost:
                 *

                 *   exit(1);
                 * }
                 * ```
                 *
                 * The reason this is problematic is because writes to `process.stdout` in Node.js
                 * are sometimes _asynchronous_ and may occur over multiple ticks of the Node.js
                 * event loop. Calling `process.exit()`, however, forces the process to exit_before_ those additional writes to `stdout` can be performed.
                 *
                 * Rather than calling `process.exit()` directly, the code _should_ set the`process.exitCode` and allow the process to exit naturally by avoiding
                 * scheduling any additional work for the event loop:
                 *
                 * ```js
                 * import process from 'process';

                 * // How to properly set the exit code while letting
                 * // the process exit gracefully.
