Items can be removed from an array in Ruby using several methods: 1) `delete` method, which removes the first occurrence of the specified value and returns true if successful or false otherwise. 2) `delete_at` method, which removes the item at the given index. 3) `pop` method, which removes and returns the last element. 4) `shift` method, which removes and returns the first element. 5) `drop` method, which returns a new array without the initial number of elements, effectively removing them from the original array.

Tell me the role of modules and mixins in ruby?
