# Copy Array Items Using slice()

- the `slice()` function must be used to return an array consisting of only `warm` and `sunny`.
- Therefore, two parameters must be passed to the `slice()` function. The first parameter must be the index you would like the substring to start at. The second parameter must be the index at which the substring ends. 
- Note: The second parameter will end the substring at that exact index.
## Example:
```javascript
return arr.slice(1, 4);
/* This will return a substring consisting of indexs [1,2,3]
    Note: arr[4] is NOT included. */
```
