Passing list values to a function

Thank you for explaining this. When I use Enum.each(posts, &IO.inspect/1), I get the following

%Post{
         id : uuid, 
         name: some name,
         feedbacks: [
                 %Comment{
                           ........
                         },

                 %Comment{
                           ........
                         }
                 ]
}
%Post{
         id : uuid, 
         name: some name,
         feedbacks: [
                 %Comment{
                           ........
                         },

                 %Comment{
                           ........
                         }
                 ]
}
%Post{
         id : uuid, 
         name: some name,
         feedbacks: [
                 %Comment{
                           ........
                         },

                 %Comment{
                           ........
                         }
                 ]
}
:ok

I am not sure how to discard this :ok. Any thoughts on how we can discard :ok?
