# `slice` Function

`slice` extracts some consecutive elements from within a list.

```hcl
slice(list, startindex, endindex)
```

`startindex` is inclusive, while `endindex` is exclusive. This function returns
an error if either index is outside the bounds of valid indices for the given
list.

## Examples

```
> slice(["a", "b", "c", "d"], 1, 3)
[
  "b",
  "c",
]
```
