Title
Body
How can I turn an array of elements into uppercase? Expected output would be: ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"] => ["MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY"] The following didn't work and left them as lower case. Day.weekday.map(&:name).each {|the_day| the_day.upcase } => ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"]
