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.

Reintroducing React: V16 and Beyond

If you think there haven’t been many changes, think again.

 
Here’s a list of the relevant changes we’ll be discussing in this course: 

- New Lifecycle Methods
- Simpler State Management with the Context API 
- ContextType - Using Context without a Consumer
- The Profiler: Using Charts and Interactions
- Lazy Loading with React.Lazy and Suspense
- Functional PureComponent with React.memo  


It goes without saying that a lot has been introduced since version 16. For your ease, each of these topics has been broken down into separate chapters.

In the next chapter, I’ll begin to discuss these changes by having a look at the new lifecycle methods available in version 16.
