# `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
```shell-session
> slice(["a", "b", "c", "d"], 1, 3)
[
"b",
"c",
]
```

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