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:
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.
