create comments in Ruby

  # This line is a comment in Ruby

This code is an example of a comment in the Ruby programming language. Comments are used to help the programmer to remember or explain what is happening in the code, and are completely ignored by the Ruby interpreter. This comment consists of the hashtag character (#) followed by some text. Everything after the hashtag is ignored, so in this case the line is simply a comment that says “This line is a comment in Ruby”. Comments can be helpful for other people reading the code, or for yourself when you come back to it in the future.
