Never Update State Directly in React

⭕ Overview In this video, we dive into one of the most common mistakes React developers make: updating state directly! 🚫 If you've ever found yourself mutating state in React without using "setState" (or the setter function in "useState"), this video is for you. I’ll explain why "state immutability" is crucial for React's performance and reactivity, and how "direct state mutation" can lead to bugs, missed re-renders, and a broken app. You'll learn the right way to update state using "setState" or "useState", ensuring your components re-render correctly and your app runs smoothly. I'll also show both "incorrect" and "correct" state updates to help you avoid common React pitfalls.
