-Which kind of boxed JS primitive is this? This module works cross-realm/iframe, does not depend on `instanceof` or mutable properties, and works despite ES6 Symbol.toStringTag.
-
-## Example
-
-```js
-var whichBoxedPrimitive = require('which-boxed-primitive');
-var assert = require('assert');
-
-// unboxed primitives return `null`
-// boxed primitives return the builtin constructor name
-
-assert.equal(whichBoxedPrimitive(undefined), null);
-assert.equal(whichBoxedPrimitive(null), null);
-
-assert.equal(whichBoxedPrimitive(false), null);
-assert.equal(whichBoxedPrimitive(true), null);
-assert.equal(whichBoxedPrimitive(new Boolean(false)), 'Boolean');
-assert.equal(whichBoxedPrimitive(new Boolean(true)), 'Boolean');
-
-assert.equal(whichBoxedPrimitive(42), null);
-assert.equal(whichBoxedPrimitive(NaN), null);
-assert.equal(whichBoxedPrimitive(Infinity), null);
-assert.equal(whichBoxedPrimitive(new Number(42)), 'Number');
-assert.equal(whichBoxedPrimitive(new Number(NaN)), 'Number');
-assert.equal(whichBoxedPrimitive(new Number(Infinity)), 'Number');
-
-assert.equal(whichBoxedPrimitive(''), null);
-assert.equal(whichBoxedPrimitive('foo'), null);
-assert.equal(whichBoxedPrimitive(new String('')), 'String');
-assert.equal(whichBoxedPrimitive(new String('foo')), 'String');
-
-assert.equal(whichBoxedPrimitive(Symbol()), null);
-assert.equal(whichBoxedPrimitive(Object(Symbol()), 'Symbol');
-
-assert.equal(whichBoxedPrimitive(42n), null);
-assert.equal(whichBoxedPrimitive(Object(42n), 'BigInt');
-
-// non-boxed-primitive objects return `undefined`
-assert.equal(whichBoxedPrimitive([]), undefined);
-assert.equal(whichBoxedPrimitive({}), undefined);
-assert.equal(whichBoxedPrimitive(/a/g), undefined);
-assert.equal(whichBoxedPrimitive(new RegExp('a', 'g')), undefined);
-assert.equal(whichBoxedPrimitive(new Date()), undefined);
-assert.equal(whichBoxedPrimitive(function () {}), undefined);
-assert.equal(whichBoxedPrimitive(function* () {}), undefined);
-assert.equal(whichBoxedPrimitive(x => x * x), undefined);
-assert.equal(whichBoxedPrimitive([]), undefined);
-

-
-Useful for libs that want to e.g. lookup a filename for a module or submodule
-that it did not `require()` itself.
-
-## Install and Usage
-
-```
-npm install --save which-module
-```
-
-```js
-const whichModule = require('which-module')
-
-console.log(whichModule(require('something')))
-// Module {
-//   id: '/path/to/project/node_modules/something/index.js',
-//   exports: [Function],
-//   parent: ...,
-//   filename: '/path/to/project/node_modules/something/index.js',
-//   loaded: true,
-//   children: [],
-//   paths: [ '/path/to/project/node_modules/something/node_modules',
-//            '/path/to/project/node_modules',
-//            '/path/to/node_modules',
-//            '/path/node_modules',
-//            '/node_modules' ] }
-```
-
-## API
-
-### `whichModule(exported)`
-
-Return the [`module` object](https://nodejs.org/api/modules.html#modules_the_module_object),
-if any, that represents the given argument in the `require.cache`.
-
-`exported` can be anything that was previously `require()`d or `import`ed as a
-module, submodule, or dependency - which means `exported` is identical to the
-`module.exports` returned by this method.
-
-If `exported` did not come from the `exports` of a `module` in `require.cache`,
-then this method returns `null`.

-## API
-
-### wrapAnsi(input, columns, [options])
-
-Wrap words to the specified column width.
-
-#### input
-
-Type: `string`
-
-String with ANSI escape codes. Like one styled by [`chalk`](https://github.com/chalk/chalk).
-
-#### columns
-
-Type: `number`
-
-Number of columns to wrap the text to.
-
-#### options
-
-Type: `Object`
-
-##### hard
-
-Type: `boolean`<br>
-Default: `false`
-
-By default the wrap is soft, meaning long words may extend past the column width. Setting this to `true` will make it hard wrap at the column width.
-
-##### wordWrap
-
-Type: `boolean`<br>

-# ws: a Node.js WebSocket library
-
-[![Version npm](https://img.shields.io/npm/v/ws.svg?logo=npm)](https://www.npmjs.com/package/ws)
-[![Linux Build](https://img.shields.io/travis/websockets/ws/master.svg?logo=travis)](https://travis-ci.org/websockets/ws)
-[![Windows Build](https://img.shields.io/appveyor/ci/lpinca/ws/master.svg?logo=appveyor)](https://ci.appveyor.com/project/lpinca/ws)
-[![Coverage Status](https://img.shields.io/coveralls/websockets/ws/master.svg)](https://coveralls.io/github/websockets/ws)
-
-ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
-server implementation.
-
-Passes the quite extensive Autobahn test suite: [server][server-report],
-[client][client-report].
-
-**Note**: This module does not work in the browser. The client in the docs is a
-reference to a back end with the role of a client in the WebSocket
-communication. Browser clients must use the native
-[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
-object. To make the same code work seamlessly on Node.js and the browser, you
-can use one of the many wrappers available on npm, like
-[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

-
-## Protocol support
-
-- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
-- **HyBi drafts 13-17** (Current default, alternatively option
-  `protocolVersion: 13`)
-
-## Installing
-
-```
-npm install ws
-```
-
-### Opt-in for performance and spec compliance
-
-There are 2 optional modules that can be installed along side with the ws
-module. These modules are binary addons which improve certain operations.
-Prebuilt binaries are available for the most popular platforms so you don't
-necessarily need to have a C++ compiler installed on your machine.
-
-- `npm install --save-optional bufferutil`: Allows to efficiently perform
-  operations such as masking and unmasking the data payload of the WebSocket
-  frames.
-- `npm install --save-optional utf-8-validate`: Allows to efficiently check if a
-  message contains valid UTF-8 as required by the spec.
-
-## API docs
-
-See [`/doc/ws.md`](./doc/ws.md) for Node.js-like docs for the ws classes.
-
-## WebSocket compression
-
-ws supports the [permessage-deflate extension][permessage-deflate] which enables
-the client and server to negotiate a compression algorithm and its parameters,
-and then selectively apply it to the data payloads of each WebSocket message.
-
-The extension is disabled by default on the server and enabled by default on the
-client. It adds a significant overhead in terms of performance and memory
-consumption so we suggest to enable it only if it is really needed.
-
-Note that Node.js has a variety of issues with high-performance compression,
-where increased concurrency, especially on Linux, can lead to [catastrophic
-memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
-permessage-deflate in production, it is worthwhile to set up a test
-representative of your workload and ensure Node.js/zlib will handle it with
-acceptable performance and memory usage.
-
-Tuning of permessage-deflate can be done via the options defined below. You can
-also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
-into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
-
-See [the docs][ws-server-options] for more options.
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({
-  port: 8080,
-  perMessageDeflate: {
-    zlibDeflateOptions: {
-      // See zlib defaults.
-      chunkSize: 1024,
-      memLevel: 7,
-      level: 3
-    },
-    zlibInflateOptions: {
-      chunkSize: 10 * 1024
-    },
-    // Other options settable:
-    clientNoContextTakeover: true, // Defaults to negotiated value.
-    serverNoContextTakeover: true, // Defaults to negotiated value.
-    serverMaxWindowBits: 10, // Defaults to negotiated value.
-    // Below options specified as default values.
-    concurrencyLimit: 10, // Limits zlib concurrency for perf.
-    threshold: 1024 // Size (in bytes) below which messages
-    // should not be compressed.
-  }
-});
-```
-
-The client will only use the extension if it is supported and enabled on the
-server. To always disable the extension on the client set the
-`perMessageDeflate` option to `false`.
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path', {
-  perMessageDeflate: false
-});
-```
-
-## Usage examples
-
-### Sending and receiving text data
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path');
-
-ws.on('open', function open() {
-  ws.send('something');
-});
-
-ws.on('message', function incoming(data) {
-  console.log(data);
-});
-```
-
-### Sending binary data
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('ws://www.host.com/path');
-
-ws.on('open', function open() {
-  const array = new Float32Array(5);
-
-  for (var i = 0; i < array.length; ++i) {
-    array[i] = i / 2;
-  }
-
-  ws.send(array);
-});
-```
-
-### Simple server
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws) {
-  ws.on('message', function incoming(message) {
-    console.log('received: %s', message);
-  });
-
-  ws.send('something');
-});
-```
-
-### External HTTP/S server
-
-```js
-const fs = require('fs');
-const https = require('https');
-const WebSocket = require('ws');
-
-const server = new https.createServer({
-  cert: fs.readFileSync('/path/to/cert.pem'),
-  key: fs.readFileSync('/path/to/key.pem')
-});
-const wss = new WebSocket.Server({ server });
-
-wss.on('connection', function connection(ws) {
-  ws.on('message', function incoming(message) {
-    console.log('received: %s', message);
-  });
-
-  ws.send('something');
-});
-
-server.listen(8080);
-```
-
-### Multiple servers sharing a single HTTP/S server
-
-```js
-const http = require('http');
-const WebSocket = require('ws');
-
-const server = http.createServer();
-const wss1 = new WebSocket.Server({ noServer: true });
-const wss2 = new WebSocket.Server({ noServer: true });
-
-wss1.on('connection', function connection(ws) {
-  // ...
-});
-
-wss2.on('connection', function connection(ws) {
-  // ...
-});
-
-server.on('upgrade', function upgrade(request, socket, head) {
-  const pathname = url.parse(request.url).pathname;
-
-  if (pathname === '/foo') {
-    wss1.handleUpgrade(request, socket, head, function done(ws) {
-      wss1.emit('connection', ws, request);
-    });
-  } else if (pathname === '/bar') {
-    wss2.handleUpgrade(request, socket, head, function done(ws) {
-      wss2.emit('connection', ws, request);
-    });
-  } else {
-    socket.destroy();
-  }
-});
-
-server.listen(8080);
-```
-
-### Server broadcast
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-// Broadcast to all.
-wss.broadcast = function broadcast(data) {
-  wss.clients.forEach(function each(client) {
-    if (client.readyState === WebSocket.OPEN) {
-      client.send(data);
-    }
-  });
-};
-
-wss.on('connection', function connection(ws) {
-  ws.on('message', function incoming(data) {
-    // Broadcast to everyone else.
-    wss.clients.forEach(function each(client) {
-      if (client !== ws && client.readyState === WebSocket.OPEN) {
-        client.send(data);
-      }
-    });
-  });
-});
-```
-
-### echo.websocket.org demo
-
-```js
-const WebSocket = require('ws');
-
-const ws = new WebSocket('wss://echo.websocket.org/', {
-  origin: 'https://websocket.org'
-});
-
-ws.on('open', function open() {
-  console.log('connected');
-  ws.send(Date.now());
-});
-
-ws.on('close', function close() {
-  console.log('disconnected');
-});
-
-ws.on('message', function incoming(data) {
-  console.log(`Roundtrip time: ${Date.now() - data} ms`);
-
-  setTimeout(function timeout() {
-    ws.send(Date.now());
-  }, 500);
-});
-```
-
-### Other examples
-
-For a full example with a browser client communicating with a ws server, see the
-examples folder.
-
-Otherwise, see the test cases.
-
-## Error handling best practices
-
-```js
-// If the WebSocket is closed before the following send is attempted
-ws.send('something');
-
-// Errors (both immediate and async write errors) can be detected in an optional
-// callback. The callback is also the only way of being notified that data has
-// actually been sent.
-ws.send('something', function ack(error) {
-  // If error is not defined, the send has been completed, otherwise the error
-  // object will indicate what failed.
-});
-
-// Immediate errors can also be handled with `try...catch`, but **note** that
-// since sends are inherently asynchronous, socket write failures will *not* be
-// captured when this technique is used.
-try {
-  ws.send('something');
-} catch (e) {
-  /* handle error */
-}
-```
-
-## FAQ
-
-### How to get the IP address of the client?
-
-The remote IP address can be obtained from the raw socket.
-
-```js
-const WebSocket = require('ws');
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws, req) {
-  const ip = req.connection.remoteAddress;
-});
-```
-
-When the server runs behind a proxy like NGINX, the de-facto standard is to use
-the `X-Forwarded-For` header.
-
-```js
-wss.on('connection', function connection(ws, req) {
-  const ip = req.headers['x-forwarded-for'].split(/\s*,\s*/)[0];
-});
-```
-
-### How to detect and close broken connections?
-
-Sometimes the link between the server and the client can be interrupted in a way
-that keeps both the server and the client unaware of the broken state of the
-connection (e.g. when pulling the cord).
-
-In these cases ping messages can be used as a means to verify that the remote
-endpoint is still responsive.
-
-```js
-const WebSocket = require('ws');
-
-function noop() {}
-
-function heartbeat() {
-  this.isAlive = true;
-}
-
-const wss = new WebSocket.Server({ port: 8080 });
-
-wss.on('connection', function connection(ws) {
-  ws.isAlive = true;
-  ws.on('pong', heartbeat);
-});
-
-const interval = setInterval(function ping() {
-  wss.clients.forEach(function each(ws) {
-    if (ws.isAlive === false) return ws.terminate();
-
-    ws.isAlive = false;
-    ws.ping(noop);
-  });
-}, 30000);
-```
-
-Pong messages are automatically sent in response to ping messages as required by
-the spec.
-
-Just like the server example above your clients might as well lose connection
-without knowing it. You might want to add a ping listener on your clients to
-prevent that. A simple implementation would be:
-
-```js
-const WebSocket = require('ws');
-
-function heartbeat() {
-  clearTimeout(this.pingTimeout);
-
-  // Use `WebSocket#terminate()` and not `WebSocket#close()`. Delay should be
-  // equal to the interval at which your server sends out pings plus a
-  // conservative assumption of the latency.
-  this.pingTimeout = setTimeout(() => {
-    this.terminate();
-  }, 30000 + 1000);
-}
-
-const client = new WebSocket('wss://echo.websocket.org/');
-
-client.on('open', heartbeat);
-client.on('ping', heartbeat);
-client.on('close', function clear() {
-  clearTimeout(this.pingTimeout);
-});
-```
-
-### How to connect via a proxy?
-
-Use a custom `http.Agent` implementation like [https-proxy-agent][] or
-[socks-proxy-agent][].

-Extend like a boss
-
-xtend is a basic utility library which allows you to extend an object by appending all of the properties from each object in a list. When there are identical properties, the right-most property takes precedence.
-
-## Examples
-
-```js
-var extend = require("xtend")
-
-// extend returns a new object. Does not mutate arguments
-var combination = extend({
-    a: "a",
-    b: "c"
-}, {
-    b: "b"
-})
-// { a: "a", b: "b" }
-```

-[![Conventional Commits](https://img.shields.io/badge/Conventional%20Commits-1.0.0-yellow.svg)](https://conventionalcommits.org)
-
-The bare-bones internationalization library used by yargs.
-
-Inspired by [i18n](https://www.npmjs.com/package/i18n).
-
-## Examples
-
-_simple string translation:_
-
-```js
-var __ = require('y18n').__
-
-console.log(__('my awesome string %s', 'foo'))
-```
-
-output:
-
-`my awesome string foo`
-
-_using tagged template literals_
-
-```js
-var __ = require('y18n').__
-var str = 'foo'
-
-console.log(__`my awesome string ${str}`)
-```
-
-output:
-
-`my awesome string foo`
-
-_pluralization support:_
-
-```js
-var __n = require('y18n').__n
-
-console.log(__n('one fish %s', '%d fishes %s', 2, 'foo'))
-```
-
-output:
-
-`2 fishes foo`
-
-## JSON Language Files
-
-The JSON language files should be stored in a `./locales` folder.
-File names correspond to locales, e.g., `en.json`, `pirate.json`.
-
-When strings are observed for the first time they will be
-added to the JSON file corresponding to the current locale.
-
-## Methods
-
-### require('y18n')(config)
-
-Create an instance of y18n with the config provided, options include:
-
-* `directory`: the locale directory, default `./locales`.
-* `updateFiles`: should newly observed strings be updated in file, default `true`.
-* `locale`: what locale should be used.
-* `fallbackToLanguage`: should fallback to a language-only file (e.g. `en.json`)
-  be allowed if a file matching the locale does not exist (e.g. `en_US.json`),
-  default `true`.
-
-### y18n.\_\_(str, arg, arg, arg)
-
-Print a localized string, `%s` will be replaced with `arg`s.
-
-This function can also be used as a tag for a template literal. You can use it
-like this: <code>__&#96;hello ${'world'}&#96;</code>. This will be equivalent to
-`__('hello %s', 'world')`.
-
-### y18n.\_\_n(singularString, pluralString, count, arg, arg, arg)
-
-Print a localized string with appropriate pluralization. If `%d` is provided
-in the string, the `count` will replace this placeholder.
-
-### y18n.setLocale(str)
-
-Set the current locale being used.
-
-### y18n.getLocale()
-
-What locale is currently being used?
-
-### y18n.updateLocale(obj)
-
-Update the current locale with the key value pairs in `obj`.

-# yallist
-
-Yet Another Linked List
-
-There are many doubly-linked list implementations like it, but this
-one is mine.
-
-For when an array would be too big, and a Map can't be iterated in
-reverse order.
-
-
-[![Build Status](https://travis-ci.org/isaacs/yallist.svg?branch=master)](https://travis-ci.org/isaacs/yallist) [![Coverage Status](https://coveralls.io/repos/isaacs/yallist/badge.svg?service=github)](https://coveralls.io/github/isaacs/yallist)
-
-## basic usage
-
-```javascript
-var yallist = require('yallist')
-var myList = yallist.create([1, 2, 3])
-myList.push('foo')
-myList.unshift('bar')
-// of course pop() and shift() are there, too
-console.log(myList.toArray()) // ['bar', 1, 2, 3, 'foo']
-myList.forEach(function (k) {
-  // walk the list head to tail
-})
-myList.forEachReverse(function (k, index, list) {
-  // walk the list tail to head
-})
-var myDoubledList = myList.map(function (k) {
-  return k + k
-})
-// now myDoubledList contains ['barbar', 2, 4, 6, 'foofoo']
-// mapReverse is also a thing
-var myDoubledListReverse = myList.mapReverse(function (k) {
-  return k + k
-}) // ['foofoo', 6, 4, 2, 'barbar']
-
-var reduced = myList.reduce(function (set, entry) {
-  set += entry
-  return set
-}, 'start')
-console.log(reduced) // 'startfoo123bar'
-```
-
-## api
-
-The whole API is considered "public".
-
-Functions with the same name as an Array method work more or less the
-same way.
-
-There's reverse versions of most things because that's the point.
-
-### Yallist
-
-Default export, the class that holds and manages a list.
-
-Call it with either a forEach-able (like an array) or a set of
-arguments, to initialize the list.
-
-The Array-ish methods all act like you'd expect.  No magic length,
-though, so if you change that it won't automatically prune or add
-empty spots.
-
-### Yallist.create(..)
-
-Alias for Yallist function.  Some people like factories.
-
-#### yallist.head
-
-The first node in the list
-
-#### yallist.tail
-
-The last node in the list
-
-#### yallist.length
-
-The number of nodes in the list.  (Change this at your peril.  It is
-not magic like Array length.)
-
-#### yallist.toArray()
-
-Convert the list to an array.
-
-#### yallist.forEach(fn, [thisp])
-
-Call a function on each item in the list.
-
-#### yallist.forEachReverse(fn, [thisp])
-
-Call a function on each item in the list, in reverse order.
-
-#### yallist.get(n)
-
-Get the data at position `n` in the list.  If you use this a lot,
-probably better off just using an Array.
-
-#### yallist.getReverse(n)
-
-Get the data at position `n`, counting from the tail.
-
-#### yallist.map(fn, thisp)
-
-Create a new Yallist with the result of calling the function on each
-item.
-
-#### yallist.mapReverse(fn, thisp)
-
-Same as `map`, but in reverse.
-
-#### yallist.pop()
-
-Get the data from the list tail, and remove the tail from the list.
-
-#### yallist.push(item, ...)
-
-Insert one or more items to the tail of the list.
-
-#### yallist.reduce(fn, initialValue)
-
-Like Array.reduce.
-
-#### yallist.reduceReverse
-
-Like Array.reduce, but in reverse.
-
-#### yallist.reverse
-
-Reverse the list in place.
-
-#### yallist.shift()
-
-Get the data from the list head, and remove the head from the list.
-
-#### yallist.slice([from], [to])
-
-Just like Array.slice, but returns a new Yallist.
-
-#### yallist.sliceReverse([from], [to])
-
-Just like yallist.slice, but the result is returned in reverse.
-
-#### yallist.toArray()
-
-Create an array representation of the list.
-
-#### yallist.toArrayReverse()
-
-Create a reversed array representation of the list.
-
-#### yallist.unshift(item, ...)
-
-Insert one or more items to the head of the list.
-
-#### yallist.unshiftNode(node)
-
-Move a Node object to the front of the list.  (That is, pull it out of
-wherever it lives, and make it the new head.)
-
-If the node belongs to a different list, then that list will remove it
-first.
-
-#### yallist.pushNode(node)
-
-Move a Node object to the end of the list.  (That is, pull it out of
-wherever it lives, and make it the new tail.)
-
-If the node belongs to a list already, then that list will remove it
-first.
-
-#### yallist.removeNode(node)
-
-Remove a node from the list, preserving referential integrity of head
-and tail and other nodes.
-
-Will throw an error if you try to have a list remove a node that
-doesn't belong to it.
-
-### Yallist.Node
-
-The class that holds the data and is actually the list.
-
-Call with `var n = new Node(value, previousNode, nextNode)`
-
-Note that if you do direct operations on Nodes themselves, it's very
-easy to get into weird states where the list is broken.  Be careful :)
-
-#### node.next
-
-The next node in the list.
-
-#### node.prev
-
-The previous node in the list.
-
-#### node.value
-
-The data the node contains.
-
-#### node.list
-
-The list to which this node belongs.  (Null if it does not belong to
-any list.)
