Lesson in the Ruby Roadmap · Stage 5: Comments

Last updated 14 September 2026

What is Comments?

Comments are notes in your code that the Ruby interpreter ignores. They're used to explain what the code does, making it easier for you and others to understand. You can create a single-line comment by starting a line with a #. For multi-line comments, you can use =begin and =end blocks; anything between these markers is treated as a comment.
