Yes, we can know this now that you say we are dealing with Strings. It would
not work, for example, with Arrays
name = "John"
lastname = "Smith"
name << lastname # => "JohnSmith"
name.chomp! lastname
name # => "John"

Note that chomp! will return nil in some situations, so don't rely on
assigning from it (if you want to do that, use the non-bang version)
