Thank you, Smith Peter! Your valuable review really gives me great strength. It's because of feedback like this that I can prepare lectures with more passion and create much better content. I will continue to meet you with even more substantial and in-depth lectures. Also, [DOM Complete Mastery Part 3] – Critical Rendering Path Perfect Analysis and Practical Optimization lecture is scheduled to be released at the end of August. Based on the understanding of events and SPA covered in this Part 2, you'll be able to perfectly master browser rendering performance and optimization as well. 😊 And whenever you have questions or need help with development, please feel free to use the open chat room below.
