A few years ago I started learning #React, I made small projects to learn it. I was a bit lost and didn't understand a few things about how React worked like React cycle-loop, memo, useEffect, to mention something.

The docs and the Internet didn't help to get a solid base. I did some courses but they didn't explain enough about the cycle-loop or useEffect

A month ago I purchased the #JoyOfReact and my base is better and I'm understanding better how React works.

TIL: The JS that goes between curly brackets in JSX can only be expressions, not statements. It has to produce a value of some kind. Which makes sense, given that we use those to show some value from our JS on the page. But having it broken down on why that is was super helpful. #JoyOfReact
