+/**
+ * The `child_process` module provides the ability to spawn subprocesses in
+ * a manner that is similar, but not identical, to [`popen(3)`](http://man7.org/linux/man-pages/man3/popen.3.html). This capability
+ * is primarily provided by the {@link spawn} function:
+ *
+ * ```js
+ * const { spawn } = require('child_process');
+ * const ls = spawn('ls', ['-lh', '/usr']);
+ *
+ * ls.stdout.on('data', (data) => {
+ *   console.log(`stdout: ${data}`);
+ * });
+ *
+ * ls.stderr.on('data', (data) => {
+ *   console.error(`stderr: ${data}`);
+ * });
+ *
+ * ls.on('close', (code) => {
+ *   console.log(`child process exited with code ${code}`);
+ * });
+ * ```
+ *
+ * By default, pipes for `stdin`, `stdout`, and `stderr` are established between
+ * the parent Node.js process and the spawned subprocess. These pipes have
+ * limited (and platform-specific) capacity. If the subprocess writes to
+ * stdout in excess of that limit without the output being captured, the
+ * subprocess blocks waiting for the pipe buffer to accept more data. This is
+ * identical to the behavior of pipes in the shell. Use the `{ stdio: 'ignore' }`option if the output will not be consumed.
+ *
+ * The command lookup is performed using the `options.env.PATH` environment
+ * variable if `env` is in the `options` object. Otherwise, `process.env.PATH` is
+ * used. If `options.env` is set without `PATH`, lookup on Unix is performed
+ * on a default search path search of `/usr/bin:/bin` (see your operating system's
+ * manual for execvpe/execvp), on Windows the current processes environment
+ * variable `PATH` is used.
+ *
+ * On Windows, environment variables are case-insensitive. Node.js
+ * lexicographically sorts the `env` keys and uses the first one that
+ * case-insensitively matches. Only first (in lexicographic order) entry will be
+ * passed to the subprocess. This might lead to issues on Windows when passing
+ * objects to the `env` option that have multiple variants of the same key, such as`PATH` and `Path`.
+ *
+ * The {@link spawn} method spawns the child process asynchronously,
+ * without blocking the Node.js event loop. The {@link spawnSync} function provides equivalent functionality in a synchronous manner that blocks
+ * the event loop until the spawned process either exits or is terminated.
+ *
+ * For convenience, the `child_process` module provides a handful of synchronous
+ * and asynchronous alternatives to {@link spawn} and {@link spawnSync}. Each of these alternatives are implemented on
+ * top of {@link spawn} or {@link spawnSync}.
+ *
+ * * {@link exec}: spawns a shell and runs a command within that
+ * shell, passing the `stdout` and `stderr` to a callback function when
+ * complete.
+ * * {@link execFile}: similar to {@link exec} except
+ * that it spawns the command directly without first spawning a shell by
+ * default.
+ * * {@link fork}: spawns a new Node.js process and invokes a
+ * specified module with an IPC communication channel established that allows
+ * sending messages between parent and child.
+ * * {@link execSync}: a synchronous version of {@link exec} that will block the Node.js event loop.
+ * * {@link execFileSync}: a synchronous version of {@link execFile} that will block the Node.js event loop.
+ *
+ * For certain use cases, such as automating shell scripts, the `synchronous counterparts` may be more convenient. In many cases, however,
+ * the synchronous methods can have significant impact on performance due to
+ * stalling the event loop while spawned processes complete.
+ * @see [source](https://github.com/nodejs/node/blob/v18.0.0/lib/child_process.js)

+         * When an IPC channel has been established between the parent and child (
+         * i.e. when using {@link fork}), the `subprocess.send()` method can
+         * be used to send messages to the child process. When the child process is a
+         * Node.js instance, these messages can be received via the `'message'` event.
+         *
+         * The message goes through serialization and parsing. The resulting
+         * message might not be the same as what is originally sent.
+         *
+         * For example, in the parent script:
+         *
+         * ```js
+         * const cp = require('child_process');
+         * const n = cp.fork(`${__dirname}/sub.js`);

+         * // Causes the child to print: CHILD got message: { hello: 'world' }
+         * n.send({ hello: 'world' });
+         * ```
+         *
+         * And then the child script, `'sub.js'` might look like this:
+         *
+         * ```js
+         * process.on('message', (m) => {
+         *   console.log('CHILD got message:', m);
+         * });
+         *
+         * // Causes the parent to print: PARENT got message: { foo: 'bar', baz: null }
+         * process.send({ foo: 'bar', baz: NaN });
+         * ```
+         *
+         * Child Node.js processes will have a `process.send()` method of their own
+         * that allows the child to send messages back to the parent.
+         *
+         * There is a special case when sending a `{cmd: 'NODE_foo'}` message. Messages
+         * containing a `NODE_` prefix in the `cmd` property are reserved for use within
+         * Node.js core and will not be emitted in the child's `'message'` event. Rather, such messages are emitted using the`'internalMessage'` event and are consumed internally by Node.js.
+         * Applications should avoid using such messages or listening for`'internalMessage'` events as it is subject to change without notice.
+         *
+         * The optional `sendHandle` argument that may be passed to `subprocess.send()` is
+         * for passing a TCP server or socket object to the child process. The child will
+         * receive the object as the second argument passed to the callback function
+         * registered on the `'message'` event. Any data that is received
+         * and buffered in the socket will not be sent to the child.
+         *
+         * The optional `callback` is a function that is invoked after the message is
+         * sent but before the child may have received it. The function is called with a
+         * single argument: `null` on success, or an `Error` object on failure.
+         *
+         * If no `callback` function is provided and the message cannot be sent, an`'error'` event will be emitted by the `ChildProcess` object. This can
+         * happen, for instance, when the child process has already exited.
+         *
+         * `subprocess.send()` will return `false` if the channel has closed or when the
+         * backlog of unsent messages exceeds a threshold that makes it unwise to send
+         * more. Otherwise, the method returns `true`. The `callback` function can be
+         * used to implement flow control.
+         *
+         * #### Example: sending a server object
+         *
+         * The `sendHandle` argument can be used, for instance, to pass the handle of
+         * a TCP server object to the child process as illustrated in the example below:
+         *
+         * ```js
+         * const subprocess = require('child_process').fork('subprocess.js');
+         *
+         * // Open up the server object and send the handle.
+         * const server = require('net').createServer();
+         * server.on('connection', (socket) => {
+         *   socket.end('handled by parent');
+         * });
+         * server.listen(1337, () => {
+         *   subprocess.send('server', server);
+         * });
+         * ```
+         *
+         * The child would then receive the server object as:
+         *
+         * ```js
+         * process.on('message', (m, server) => {
+         *   if (m === 'server') {
+         *     server.on('connection', (socket) => {
+         *       socket.end('handled by child');
+         *     });
+         *   }
+         * });
+         * ```
+         *
+         * Once the server is now shared between the parent and child, some connections
+         * can be handled by the parent and some by the child.
+         *
+         * While the example above uses a server created using the `net` module, `dgram`module servers use exactly the same workflow with the exceptions of listening on
+         * a `'message'` event instead of `'connection'` and using `server.bind()` instead
+         * of `server.listen()`. This is, however, currently only supported on Unix
+         * platforms.
+         *
+         * #### Example: sending a socket object
+         *
+         * Similarly, the `sendHandler` argument can be used to pass the handle of a
+         * socket to the child process. The example below spawns two children that each
+         * handle connections with "normal" or "special" priority:
+         *
+         * ```js
+         * const { fork } = require('child_process');
+         * const normal = fork('subprocess.js', ['normal']);
+         * const special = fork('subprocess.js', ['special']);
+         *
+         * // Open up the server and send sockets to child. Use pauseOnConnect to prevent
+         * // the sockets from being read before they are sent to the child process.
+         * const server = require('net').createServer({ pauseOnConnect: true });
+         * server.on('connection', (socket) => {
+         *
+         *   // If this is special priority...
+         *   if (socket.remoteAddress === '74.125.127.100') {
+         *     special.send('socket', socket);
+         *     return;
+         *   }
+         *   // This is normal priority.
+         *   normal.send('socket', socket);
+         * });
+         * server.listen(1337);
+         * ```
+         *
+         * The `subprocess.js` would receive the socket handle as the second argument
+         * passed to the event callback function:
+         *
+         * ```js
+         * process.on('message', (m, socket) => {
+         *   if (m === 'socket') {
+         *     if (socket) {
+         *       // Check that the client socket exists.
+         *       // It is possible for the socket to be closed between the time it is
+         *       // sent and the time it is received in the child process.
+         *       socket.end(`Request handled with ${process.argv[2]} priority`);
+         *     }
+         *   }
+         * });
+         * ```
+         *
+         * Do not use `.maxConnections` on a socket that has been passed to a subprocess.
+         * The parent cannot track when the socket is destroyed.
+         *
+         * Any `'message'` handlers in the subprocess should verify that `socket` exists,
+         * as the connection may have been closed during the time it takes to send the
+         * connection to the child.

+     * If not given, the default is to inherit the current working directory. If given,
+     * but the path does not exist, the child process emits an `ENOENT` error
+     * and exits immediately. `ENOENT` is also emitted when the command
+     * does not exist.
+     *
+     * Use `env` to specify environment variables that will be visible to the new
+     * process, the default is `process.env`.
+     *
+     * `undefined` values in `env` will be ignored.
+     *
+     * Example of running `ls -lh /usr`, capturing `stdout`, `stderr`, and the

+     *
+     * ```js
+     * const { spawn } = require('child_process');

+     *   }
+     * });
+     * ```
+     *
+     * Example of checking for failed `spawn`:

+     * ```
+     *
+     * Certain platforms (macOS, Linux) will use the value of `argv[0]` for the process
+     * title while others (Windows, SunOS) will use `command`.
+     *
+     * Node.js currently overwrites `argv[0]` with `process.execPath` on startup, so`process.argv[0]` in a Node.js child process will not match the `argv0`parameter passed to `spawn` from the parent,
+     * retrieve it with the`process.argv0` property instead.
+     *
+     * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
+     * the error passed to the callback will be an `AbortError`:
+     *
+     * ```js

+     * const controller = new AbortController();
+     * const { signal } = controller;

+     * });

+     * The `child_process.fork()` method is a special case of {@link spawn} used specifically to spawn new Node.js processes.
+     * Like {@link spawn}, a `ChildProcess` object is returned. The
+     * returned `ChildProcess` will have an additional communication channel
+     * built-in that allows messages to be passed back and forth between the parent and
+     * child. See `subprocess.send()` for details.
+     *
+     * Keep in mind that spawned Node.js child processes are
+     * independent of the parent with exception of the IPC communication channel
+     * that is established between the two. Each process has its own memory, with
+     * their own V8 instances. Because of the additional resource allocations
+     * required, spawning a large number of child Node.js processes is not
+     * recommended.
+     *
+     * By default, `child_process.fork()` will spawn new Node.js instances using the `process.execPath` of the parent process. The `execPath` property in the`options` object allows for an alternative
+     * execution path to be used.
+     *
+     * Node.js processes launched with a custom `execPath` will communicate with the
+     * parent process using the file descriptor (fd) identified using the
+     * environment variable `NODE_CHANNEL_FD` on the child process.
+     *
+     * Unlike the [`fork(2)`](http://man7.org/linux/man-pages/man2/fork.2.html) POSIX system call, `child_process.fork()` does not clone the
+     * current process.
+     *
+     * The `shell` option available in {@link spawn} is not supported by`child_process.fork()` and will be ignored if set.
+     *
+     * If the `signal` option is enabled, calling `.abort()` on the corresponding`AbortController` is similar to calling `.kill()` on the child process except
+     * the error passed to the callback will be an `AbortError`:
+     *
+     * ```js
+     * if (process.argv[2] === 'child') {
+     *   setTimeout(() => {
+     *     console.log(`Hello from ${process.argv[2]}!`);
+     *   }, 1_000);

+/**
+ * The `console` module provides a simple debugging console that is similar to the
+ * JavaScript console mechanism provided by web browsers.
+ *
+ * The module exports two specific components:
+ *
+ * * A `Console` class with methods such as `console.log()`, `console.error()` and`console.warn()` that can be used to write to any Node.js stream.
+ * * A global `console` instance configured to write to `process.stdout` and `process.stderr`. The global `console` can be used without calling`require('console')`.
+ *
+ * _**Warning**_: The global console object's methods are neither consistently
+ * synchronous like the browser APIs they resemble, nor are they consistently
+ * asynchronous like all other Node.js streams. See the `note on process I/O` for
+ * more information.
+ *
+ * Example using the global `console`:
+ *
+ * ```js
+ * console.log('hello world');
+ * // Prints: hello world, to stdout
+ * console.log('hello %s', 'world');
+ * // Prints: hello world, to stdout
+ * console.error(new Error('Whoops, something bad happened'));
+ * // Prints error message and stack trace to stderr:
+ * //   Error: Whoops, something bad happened
+ * //     at [eval]:5:15
+ * //     at Script.runInThisContext (node:vm:132:18)
+ * //     at Object.runInThisContext (node:vm:309:38)
+ * //     at node:internal/process/execution:77:19
+ * //     at [eval]-wrapper:6:22
+ * //     at evalScript (node:internal/process/execution:76:60)
+ * //     at node:internal/main/eval_string:23:3
+ *
+ * const name = 'Will Robinson';
+ * console.warn(`Danger ${name}! Danger!`);
+ * // Prints: Danger Will Robinson! Danger!, to stderr
+ * ```
+ *
+ * Example using the `Console` class:
+ *
+ * ```js
+ * const out = getStreamSomehow();
+ * const err = getStreamSomehow();
+ * const myConsole = new console.Console(out, err);
+ *
+ * myConsole.log('hello world');
+ * // Prints: hello world, to out
+ * myConsole.log('hello %s', 'world');
+ * // Prints: hello world, to out
+ * myConsole.error(new Error('Whoops, something bad happened'));
+ * // Prints: [Error: Whoops, something bad happened], to err
+ *
+ * const name = 'Will Robinson';
+ * myConsole.warn(`Danger ${name}! Danger!`);

+ * ```
+ *
+ * All other functions in the `dns` module connect to an actual DNS server to
+ * perform name resolution. They will always use the network to perform DNS
+ * queries. These functions do not use the same set of configuration files used by {@link lookup} (e.g. `/etc/hosts`). Use these functions to always perform

+/**
+ * Much of the Node.js core API is built around an idiomatic asynchronous
+ * event-driven architecture in which certain kinds of objects (called "emitters")
+ * emit named events that cause `Function` objects ("listeners") to be called.
+ *
+ * For instance: a `net.Server` object emits an event each time a peer
+ * connects to it; a `fs.ReadStream` emits an event when the file is opened;
+ * a `stream` emits an event whenever data is available to be read.
+ *
+ * All objects that emit events are instances of the `EventEmitter` class. These
+ * objects expose an `eventEmitter.on()` function that allows one or more
+ * functions to be attached to named events emitted by the object. Typically,
+ * event names are camel-cased strings but any valid JavaScript property key
+ * can be used.
+ *
+ * When the `EventEmitter` object emits an event, all of the functions attached
+ * to that specific event are called _synchronously_. Any values returned by the
+ * called listeners are _ignored_ and discarded.
+ *
+ * The following example shows a simple `EventEmitter` instance with a single
+ * listener. The `eventEmitter.on()` method is used to register listeners, while
+ * the `eventEmitter.emit()` method is used to trigger the event.
+ *
+ * ```js
+ * const EventEmitter = require('events');
+ *
+ * class MyEmitter extends EventEmitter {}
+ *
+ * const myEmitter = new MyEmitter();
+ * myEmitter.on('event', () => {

+/**
+ * To use the HTTP server and client one must `require('http')`.
+ *
+ * The HTTP interfaces in Node.js are designed to support many features
+ * of the protocol which have been traditionally difficult to use.
+ * In particular, large, possibly chunk-encoded, messages. The interface is
+ * careful to never buffer entire requests or responses, so the
+ * user is able to stream data.
+ *
+ * HTTP message headers are represented by an object like this:
+ *
+ * ```js
+ * { 'content-length': '123',
+ *   'content-type': 'text/plain',
+ *   'connection': 'keep-alive',
+ *   'host': 'example.com',
+ *   'accept': '*' }
+ * ```
+ *
+ * Keys are lowercased. Values are not modified.
+ *
+ * In order to support the full spectrum of possible HTTP applications, the Node.js
+ * HTTP API is very low-level. It deals with stream handling and message
+ * parsing only. It parses a message into headers and body but it does not
+ * parse the actual headers or the body.
+ *
+ * See `message.headers` for details on how duplicate headers are handled.
+ *
+ * The raw headers as they were received are retained in the `rawHeaders`property, which is an array of `[key, value, key2, value2, ...]`. For
+ * example, the previous message header object might have a `rawHeaders`list like the following:
+ *
+ * ```js
+ * [ 'ConTent-Length', '123456',
+ *   'content-LENGTH', '123',
+ *   'content-type', 'text/plain',
+ *   'CONNECTION', 'keep-alive',
+ *   'Host', 'example.com',
+ *   'accepT', '*' ]

+     * or put into a pool where it is kept to be used again for requests to the
+     * same host and port. Whether it is destroyed or pooled depends on the`keepAlive` `option`.
+     *
+     * Pooled connections have TCP Keep-Alive enabled for them, but servers may

+     * over the same connection, in which case the connection will have to be
+     * remade for every request and cannot be pooled. The `Agent` will still make
+     * the requests to that server, but each one will occur over a new connection.
+     *
+     * When a connection is closed by the client or the server, it is removed
+     * from the pool. Any unused sockets in the pool will be unrefed so as not
+     * to keep the Node.js process running when there are no outstanding requests.
+     * (see `socket.unref()`).
+     *
+     * It is good practice, to `destroy()` an `Agent` instance when it is no
+     * longer in use, because unused sockets consume OS resources.
+     *
+     * Sockets are removed from an agent when the socket emits either
+     * a `'close'` event or an `'agentRemove'` event. When intending to keep one
+     * HTTP request open for a long time without keeping it in the agent, something

+     * An agent may also be used for an individual request. By providing`{agent: false}` as an option to the `http.get()` or `http.request()`functions, a one-time use `Agent` with default options
+     * will be used
+     * for the client connection.

+     *
+     * If any error is encountered during the request (be that with DNS resolution,
+     * TCP level errors, or actual HTTP parse errors) an `'error'` event is emitted
+     * on the returned request object. As with all `'error'` events, if no listeners
+     * are registered the error will be thrown.
+     *
+     * There are a few special headers that should be noted.
+     *
+     * * Sending a 'Connection: keep-alive' will notify Node.js that the connection to
+     * the server should be persisted until the next request.
+     * * Sending a 'Content-Length' header will disable the default chunked encoding.
+     * * Sending an 'Expect' header will immediately send the request headers.
+     * Usually, when sending 'Expect: 100-continue', both a timeout and a listener
+     * for the `'continue'` event should be set. See RFC 2616 Section 8.2.3 for more
+     * information.
+     * * Sending an Authorization header will override using the `auth` option
+     * to compute basic authentication.
+     *
+     * Example using a `URL` as `options`:
+     *
+     * ```js
+     * const options = new URL('http://abc:xyz@example.com');
+     *
+     * const req = http.request(options, (res) => {
+     *   // ...
+     * });
+     * ```
+     *
+     * In a successful request, the following events will be emitted in the following

+     * * `'socket'`
+     * * `'response'`
+     *    * `'data'` any number of times, on the `res` object
