dgh12's honest review, Real-world web performance optimization for frontend developers (feat. React) - Part. 2 course

This time, I took the course along with Part 1. When it comes to optimization, I often searched Google and got frustrated because I didn't understand it, but the rich examples and kind explanations helped me a lot. Thank you for releasing a good course, and I will definitely listen to the next series if it comes out^^
