A note on framework specifics

As a final note, before I send you into the rest of the book/course, I want to touch on a few points about these frameworks:

  • React has two different ways of writing code: Using classes and "Hooks".

While React classes are more similar to Angular or Vue's Option API, I've decided to write this book/course using React's "Hooks" method as references for the components.

This is because, while classes are still a part of the most modern versions of React, they've drastically fallen out of favor in comparison to React Hooks. I want to try to make this book representative of real-world codebases you're likely to run into with modern versions of these frameworks, so I thought it only made sense to go with Hooks.
