The lecture quality is not satisfactory. While it's good that it covers the latest tech stack content and utilizes AI, you're being too lazy with it. The explanations just read directly from the lecture materials, and when you don't know something, you just tell us to read the official documentation or figure it out ourselves. I felt there was insufficient explanation about the logic behind auto-completion with the tab key. Sure, copy-pasting is convenient, but it's disappointing that you only explain the principles of logic and code examples verbally without conducting actual hands-on practice. (Everyone, try it yourselves!!) I think this is a lecture with poor cost-effectiveness.
