Inside the paid Advanced React.js course are lectures on various advanced React.js component patterns. We've pulled them out into their own free course here.
These videos represent only about 20% of the advanced course.
Deepen your understanding by enrolling in the full Advanced React.js course. You'll gain access to hands-on, real-world exercises and detailed video solutions, you'll also learn to reimplement the two most popular libraries in React: React Redux and React Router.
Or, just enjoy the free videos in this course :)
