Excellent course! David does a great job. His style and content are very engaging, and his ability to demistify things other teachers gloss over makes this course #1 in my book.

Amazing course, not only serves as an approach for TDD but also refreshes a lot of React / Redux concepts on the road. Really enjoyed it, great work and thanks!
