# [Copy Array Items Using slice()](https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-data-structures/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. */

```
