Here is another way to do that…

array = [“1”,“3”,“4”]
array.collect do |n|
n.to_i
end

It will return you a new integer array
[1, 3, 4]

If you want to change your array in place then just put an exclamation
mark
after the method collect like this…

array.collect! do |n|

No need to do this…

array.map!{|e| e.to_i}

you can do this with the first code also with a change…

array.map!(&:to_i)
