Gain insights into React updates since V16, including new lifecycle methods, context API, and hooks. Discover how to utilize these features for writing better modern React applications.

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? How important are they for your day to day use?

This course is your one-stop reference to most important React updates since V16 was released. We’ll walk through all the major features of modern React so you can stay in sync with the most recent changes while learning to write better software.
