"Compliment", not "Complement"

Great class. Thank you the effort! The flow is just what a beginner needs.

One of the major examples misspells "compliment" (opposite of insult) as "complement" (something that enhances or completes something else) in the chapter text and the code.

There are other minor typos -- I will file those as time allows.

Search the chapter text and example code for the misspelled word "complement"; the payload does not name specific files or tests. Replace the occurrence referring to an insult with "compliment", then review the surrounding example and documentation to confirm the spelling is correct in both places.
