Thanks Bruno for noticing my mistake, you’re right. Of course, I agree that they work different way, but in simple cases (which are most common) they have the same results. Both can do the things, which would be very tricky do with the second one (as you presented):

e.g. “hello”.tr(‘a-y’, ‘b-z’) “hello”.gsub(/([aeiou])/, ‘<\1>‘)

Hi,

I just want to warn you that your two examples are not exactly similar:

“heloo knapo”.tr(‘o’,’ik’) => “helii knapi” “heloo knapo”.gsub(‘o’,’ik’) => “helikik knapik”

But tr also have some other capabilities, like swapping ‘i’ and ‘o’:

“heloo knapi”.tr(‘io’,’oi’) => “helii knapo”
