I kept putting off studying Next.js, but I was drawn to this course by the visual materials that seemed like they would explain things easily. It took me three weeks to complete the entire course. The best part was how you clearly showed the entire operational process between the back-end server, Next server, browser, and user when explaining concepts. Also, since you provided comparative explanations as if constantly reviewing, I was able to correct myself whenever I misunderstood or felt confused. Thank you for explaining such a vast amount of content in a way that is easy to understand. Thanks to you, I had an enjoyable introduction to Next.js.
