This is an excellent course. I've never seen a course this in-depth on Inflearn before. I could understand why Next.js was designed this way. Just trying things out without meaningful study doesn't stick in your memory even after a short time. Learning *why* it was designed this way helps it stick in your memory for a long time. It also naturally helps with interview prep. As someone who wasted a lot of money on follow-along project courses, I highly recommend this in-depth course.
