# Reversing A List
|
|
|
|
To efficiently work with and _transform_ lists in Elixir, you will likely
|
|
need utilize a list reversing function from time to time. Your best bet is
|
|
to reach for the Erlang implementation which is available as part of the
|
|
`lists` module.
|
|
|
|
Here are a couple examples of how to use it:
|
|
|
|
```elixir
|
|
> :lists.reverse([1,2,3])
|
|
[3, 2, 1]
|
|
> :lists.reverse([1, :a, true, "what", 5])
|
|
[5, "what", true, :a, 1]
|
|
```
|
|
|
|
Note: though I said "_transform_ lists" above, what is actually going on is
|
|
that a new version of the list representing my transformation is being
|
|
created, per Elixir's functional nature.
