Functionite company did an impressive job bringing JavaScript expert Kyle Simpson to their hometown Warsaw, Poland in September last year. He led You Don’t Know JS Workshops, 5 days of JavaScript classes focused on learning new skills and the best practices. I joined on the last day to attend an excellent workshop titled Functional-Light JavaScript. In this post, I wanted to share slides and my coding exercises from this course. If you are curious what topics related to functional programming were covered I strongly recommend checking notes from a similar workshop shared by Beth Allchurch.
