- React is a library for development of single page web applications
- Each part of a React application is split into components
- Each component is written in JSX (HTML & Javascript combined)
- Small function based components are the way to go!
- Use hooks to give you stateful behaviour
- Global state libraries can be used to save you from props tree trap!
- There are loads of libraries out there, always google before implementing something yourself ;-)
- FOr example this UI uses the material-ui package for all its styling
A React Component Tree might look like this:
- In the background React efficiently re-renders your components on the page
- It only re-renders the parts of the page that it needs to
- Individual components will be re-rendered when their props or state values change
