React Performance Optimization Patterns Course
React makes it easy to build UIs, but building fast React apps is a different skill altogether.In this hands-on, real-world React Performance Optimization crash course, you’ll learn how React actually re-renders, why your app slows down, and which performance patterns truly matter in production — not just theory, but battle-tested techniques used by senior engineers.
This video is about knowing what to optimize, when to optimize, and how to do it right.
