You can delete all even numbers from an array in Ruby, by using the Array#delete_if
method, for example, like so:
numbers = [5, 10, 26, 44, 75] numbers.delete_if { | item | item.even? } print numbers #=> [5, 75]
This would leave only odd numbers in the original array.
You could also shorten this by using the &:
syntax, for example, like so:
print numbers.delete_if(&:even?) #=> [5, 75]
The Array#delete_if
method would mutate (i.e. modify) the original array. If you wish to instead return a new array with only odd values (in an array of integers), then you can consider using the Array#select
method instead.
