Lewis has really catered this course to the modern concepts and I enjoyed the references and subtle jokes.
Think a lot of programmers learn about patterns in varsity or some training, get thrown into the deep end of an organization with its set ways of doing things. This course was extremely informative and a nice refresher and new take on patterns.

One thing that I take away is the emphasis on patterns being widely useful no matter the language, patterns not being a 100% fit for each scenario but rather a guide on how to approach design.
Thanks again as always Lewis!
