# `slice` Function

-> **Note:** This page is about Terraform 0.12 and later. For Terraform 0.11 and
earlier, see
[0.11 Configuration Language: Interpolation Syntax](../../configuration-0-11/interpolation.html).

`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",
]
```

  string, although it uses a length instead of an end index.
