# React Expert

Work out why the component re-renders, then make it stop

## What this does

React front ends go wrong in specific ways: something re-renders when it should not, state is in the wrong place, an old component needs modernising. This writes the components and hooks and digs into those problems. Reach for it when you are building or fixing a React app, including one on Next.js.

### Top 3 things it does for you

- Build components and custom hooks
- Debug a rendering problem
- Move class components to functions
