	Called with the plain request options, right before their normalization.

	The second argument represents the current `Options` instance.

	@default []

	**Note:**
	> - This hook must be synchronous.

	**Note:**
	> - This is called every time options are merged.

	**Note:**
	> - The `options` object may not have the `url` property. To modify it, use a `beforeRequest` hook instead.

	**Note:**
	> - This hook is called when a new instance of `Options` is created.
	> - Do not confuse this with the creation of `Request` or `got(…)`.

	**Note:**
	> - When using `got(url)` or `got(url, undefined, defaults)` this hook will **not** be called.

	This is especially useful in conjunction with `got.extend()` when the input needs custom handling.

	For example, this can be used to fix typos to migrate from older versions faster.

	@example
	```
	import got from 'got';

	const instance = got.extend({
		hooks: {
			init: [
				plain => {
					if ('followRedirects' in plain) {
						plain.followRedirect = plain.followRedirects;
						delete plain.followRedirects;
					}
				}
			]
		}
	});

	// Normally, the following would throw:
	const response = await instance(
		'https://example.com',
		{
			followRedirects: true
		}
	);

	// There is no option named `followRedirects`, but we correct it in an `init` hook.
	```

	Or you can create your own option and store it in a context:

	```
	import got from 'got';

	const instance = got.extend({
		hooks: {
			init: [
				(plain, options) => {
					if ('secret' in plain) {
						options.context.secret = plain.secret;
						delete plain.secret;
					}
				}
			],
			beforeRequest: [
				options => {
					options.headers.secret = options.context.secret;
				}
			]
		}
	});

	const {headers} = await instance(
		'https://httpbin.org/anything',
		{
			secret: 'passphrase'
		}
	).json();

	console.log(headers.Secret);
	//=> 'passphrase'
	```
	*/
	init: InitHook[];

	/**
	Called right before making the request with `options.createNativeRequestOptions()`.

	This hook is especially useful in conjunction with `got.extend()` when you want to sign your request.

	@default []

	**Note:**
	> - Got will make no further changes to the request before it is sent.

	**Note:**
	> - Changing `options.json` or `options.form` has no effect on the request. You should change `options.body` instead. If needed, update the `options.headers` accordingly.

	@example
	```
	import got from 'got';

	const response = await got.post(
		'https://httpbin.org/anything',
		{
			json: {payload: 'old'},
			hooks: {
				beforeRequest: [
					options => {
						options.body = JSON.stringify({payload: 'new'});
						options.headers['content-length'] = options.body.length.toString();
					}
				]
			}
		}
	);
	```

	**Tip:**
	> - You can indirectly override the `request` function by early returning a [`ClientRequest`-like](https://nodejs.org/api/http.html#http_class_http_clientrequest) instance or a [`IncomingMessage`-like](https://nodejs.org/api/http.html#http_class_http_incomingmessage) instance. This is very useful when creating a custom cache mechanism.

Delays between retries counts with function `1000 * Math.pow(2, retry) + Math.random() * 100`, where `retry` is attempt number (starts from 1).

The `calculateDelay` property is a `function` that receives an object with `attemptCount`, `retryOptions`, `error` and `computedValue` properties for current retry count, the retry options, error and default computed value.
The function must return a delay in milliseconds (or a Promise resolving with it) (`0` return value cancels retry).

By default, it retries *only* on the specified methods, status codes, and on these network errors:
- `ETIMEDOUT`: One of the [timeout](#timeout) limits were reached.
- `ECONNRESET`: Connection was forcibly closed by a peer.
- `EADDRINUSE`: Could not bind to any free port.
- `ECONNREFUSED`: Connection was refused by the server.
- `EPIPE`: The remote side of the stream being written has been closed.
- `ENOTFOUND`: Couldn't resolve the hostname to an IP address.
- `ENETUNREACH`: No internet connection.
- `EAI_AGAIN`: DNS lookup timed out.

__Note:__ Got does not retry on `POST` by default.
__Note:__ If `maxRetryAfter` is set to `undefined`, it will use `options.timeout`.
__Note:__ If [`Retry-After`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Retry-After) header is greater than `maxRetryAfter`, it will cancel the request.

	__Note__: `prefixUrl` will be ignored if the `url` argument is a URL instance.

	__Note__: Leading slashes in `input` are disallowed when using this option to enforce consistency and avoid confusion.
	For example, when the prefix URL is `https://example.com/foo` and the input is `/bar`, there's ambiguity whether the resulting URL would become `https://example.com/foo/bar` or `https://example.com/bar`.
	The latter is used by browsers.

	__Tip__: Useful when used with `got.extend()` to create niche-specific Got instances.

	__Tip__: You can change `prefixUrl` using hooks as long as the URL still includes the `prefixUrl`.
