This course is a hidden gem for anyone who wants to learn TS. Has so much information. With that being said, you need to do a lot of practice to remember the stuff in this course, and I think you will come back here more often to check up on certain things. With that being said take notes and code on :)

I would have preferred a longer practical part at the end of the course (the examples were a bit abstract)
