🔠 Common String Methods

Ruby provides many handy methods like upcase, downcase, capitalize, and reverse. These return new strings and do not change the original unless you use the bang version (e.g., upcase!).

s = "ruby"
puts s.upcase        # => "RUBY"
puts s.capitalize    # => "Ruby"
puts "Madam".reverse  # => "madaM"
