# `reverse` 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).

`reverse` takes a sequence and produces a new sequence of the same length
with all of the same elements as the given sequence but in reverse order.

## Examples

```
> reverse([1, 2, 3])
[
  3,
  2,
  1,
]
```
