Hi! I made this free ebook about React. It's a 220 pages long comprehensive guide to learn React, in PDF, ePub and Mobi formats!

I hope this helps moving from zero to having a good grasp of what React is and how to work with it.

You can get it from here: https://reacthandbook.com

Let me know what you think of it!

I really like to write implicitly returned anonymous functions like:

const example = (stuff) => stuff;

But in my ignorance to quickly debug my function I would then tediously convert it like so:

const example = (stuff) => {
  console.log(stuff);
  return stuff;
}

That, however, was before I discovered the Comma Operator! Long story short it evaluates each expression but only returns the last. So therefore you can write that quick, messy debug instead like so:

const example = (stuff) => (console.log(stuff), stuff);

Hopefully I wasn't the only other person in the world doing this, and someone finds it helpful!
