Ruby’s string class offers a few methods to change the case of a string.
Upcase is used to capitalize every letter of a string.
Downcase is used to make every letter in a string lowercase.
Another method on the string class is capitalize. This method capitalizes the first letter of a string while downcasing the remaining letters.
Titleize capitalizes every word in a string. Remember you can only use this if you are working within the Rails framework (or just the ActiveSupport gem).
name = “jaKe JoNes” name.titleize
