Specify a custom error message or error to throw when it times out:
- `message: 'too slow'` will throw `TimeoutError('too slow')`
- `message: new MyCustomError('its over 9000')` will throw the same error instance
- `message: false` will make the promise resolve with `undefined` instead of rejecting

import {TimeoutError} from 'p-timeout';
class MyCustomError extends TimeoutError {

import sinon from 'sinon';
const originalSetTimeout = setTimeout;
const originalClearTimeout = clearTimeout;
sinon.useFakeTimers();
// Use `pTimeout` without being affected by `sinon.useFakeTimers()`:

/**
Timeout a promise after a specified amount of time.
If you pass in a cancelable promise, specifically a promise with a `.cancel()` method, that method will be called when the `pTimeout` promise times out.
@param input - Promise to decorate.
@returns A decorated `input` that times out after `milliseconds` time. It has a `.clear()` method that clears the timeout.
@example
```
import {setTimeout} from 'node:timers/promises';
import pTimeout from 'p-timeout';
const delayedPromise = () => setTimeout(200);
await pTimeout(delayedPromise(), {
milliseconds: 50,
fallback: () => {
return pTimeout(delayedPromise(), {milliseconds: 300});
