The explanations are excellent and very helpful for learning about optimization, but I would appreciate it if the course could be updated as it is a bit old. The "Audits" tab in DevTools was integrated into "Lighthouse" a long time ago, and it’s a bit disappointing that it still explains outdated compression methods like Gzip and deflate—which are practically relics—even though Brotli (br) has been out for a while and is superior to Gzip.

This is such an old video ㅜ

Good

This is a really great course for organizing the fundamentals~

I really enjoyed it!
