	Returns a `Promise` that is fulfilled when calling `input` returns a fulfilled promise. If calling `input` returns a rejected promise, `input` is called again until the max retries are reached, it then rejects with the last rejection reason.

	Does not retry on most `TypeErrors`, with the exception of network errors. This is done on a best case basis as different browsers have different [messages](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch#Checking_that_the_fetch_was_successful) to indicate this. 
	See [whatwg/fetch#526 (comment)](https://github.com/whatwg/fetch/issues/526#issuecomment-554604080)

	@param input - Receives the number of attempts as the first argument and is expected to return a `Promise` or any value.
	@param options - Options are passed to the [`retry`](https://github.com/tim-kos/node-retry#retryoperationoptions) module.

	@example
	```
	import pRetry = require('p-retry');
	import fetch from 'node-fetch';

	const run = async () => {
		const response = await fetch('https://sindresorhus.com/unicorn');

		// Abort retrying if the resource doesn't exist
		if (response.status === 404) {
			throw new pRetry.AbortError(response.statusText);
		}

		const result = await pRetry(run, {
			onFailedAttempt: error => {
				console.log(`Attempt ${error.attemptNumber} failed. There are ${error.retriesLeft} retries left.`);
				// 1st request => Attempt 1 failed. There are 4 retries left.
				// 2nd request => Attempt 2 failed. There are 3 retries left.
