Coming from a Ruby on Rails background, I had to pretty much learn React on the job and it was always hard to find the right patterns and don't even get me started on testing! After taking both EpicReact and TestingJs courses I got a much better understanding of the tradeoffs and benefits of each pattern and on the road I also had fun learning fundamental web things I inadvertedly had been neglecting. KCD takes you back from Tutorial Hell!
