Unlike other programming languages, Ruby has p, print, puts to print out information to the command line. For Ruby beginners, it might be a little bit confusing to figure out when to use what. print calls to_s on the object, it doesn’t append a new line. > print 1,2,3
123 => nil puts call to_s and add a new line to the output > puts 1,2,3
1
2
3
=> nil p calls inspect method and adds a new line. p is more useful for debugging, as it returns the original data type.
