Remove an element from an array in Ruby

In Ruby we have multiple options for removing an element from an array. If we wish to do so by matching a given value we can use reject! or delete_if. This removes all the matching values from the array.

toppings = [
  'mozzarella',
  'tomato',
  'salami',
  'pineapple'
]

toppings.reject! { |n| n == 'pineapple' }
puts toppings.inspect
#=> ["mozzarella", "tomato", "salami"]
