To guard against crashing the Node.js process, a listener can be registered
on the [`process` object's `uncaughtException` event][] or the [`domain`][] module
can be used. (Note, however, that the `domain` module has been deprecated.)
```js
const myEmitter = new MyEmitter();
process.on('uncaughtException', (err) => {
console.error('whoops! there was an error');
});
myEmitter.emit('error', new Error('whoops!'));
// Prints: whoops! there was an error
```
To guard against crashing the Node.js process the [`domain`][] module can be
used. (Note, however, that the `domain` module has been deprecated.)
As a best practice, listeners should always be added for the `'error'` events.
