I think this is one of the best courses I've seen on Inflearn..!! The theoretical parts are not lacking at all, and I think you can learn a great deal across the board, from example code to hands-on practice. When explaining the concept of Source, I found it even more impressive that you implemented it without using external storage or MSQ. If you had covered that part, it probably would have deviated somewhat from the course objectives. I really enjoyed the course. I'm learning so much from it.
