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:
> :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.
