What’s new with React? New lifecycle methods, context API, hooks, and lots more. While the fundamental principles of React have stayed the same, the way we write React apps has changed with each new release. If you learned React a while back, it’s possible that you haven’t been up to date with every new feature/release. It’s also possible to get lost in all the new features. Where exactly do you start?
