Modern React with Every React Update Since v16 Demystified (includes advanced hooks)
About the Book
I wrote my first React application 3 to 4 years ago. Between then and now, the fundamental principles of React have remained the same. React is just as declarative and component-based today as it was then.
That’s great news, however, the way we write React applications today has changed!
There’s been a lot of new additions (and well, removals).
If you learned React a while back it’s not impossible that you haven’t been up to date with every new feature/release. It’s also possible to get lost on all the new features. Where exactly do you start? How important are they for your day to day use?
Modern React has new interesting features that are worth your attention. It’s best to know those now, and not have to unlearn and relearn newer concepts.
Whether you’ve been writing React for a while, or new to developing React applications, I will be discussing **every** update to React since version 16.
This will keep you in sync with the recent changes to React, and help you write better software.
Remember, a reintroduction to React is important for not just beginners, but professionals alike. It all depends on how well you’ve kept your ear to the ground, and really studied the many changes that have been released over the last 12 months.
On the bright side, I’m bringing you a one-stop reference to all the changes. From the new lifecycle methods to advanced hooks and reusable component patterns with hooks.
In this book, I’ll take you on a journey — alongside some humour and unique content to follow.
The question is, are you ready to go on this journey with me?
