About the author

Chris Laux has been a programmer for many years, lately working with JavaScript, Go and Python. His interest in programming started in childhood when he discovered BASIC and Pascal for MS DOS. He believes the static display of algorithms and data structures in conventional textbooks and web pages can be much improved using modern animation techniques. He lives in the town of Nürnberg, Germany.
