In Ruby you have some tricks in the console. I always use the _ to retrieve the last return value.
In Elixir, you have the same approach with v function. Let’s see:
iex help for v function
As you can see, the function v can get the last value because it’s using the default value -1 or you can use v(line_number) to get the value from a previous one.
