The conversation between human and AI assistant.
[|Human|] How can the following code be improved for readability?
[|AI|] A more efficient and readable version of this code for doubling values of an array could be written using the map() method:

```javascript
list = list.map(value => value * 2);
```

This will return a new array with doubled values of the original `list`.
