Learn React Hooks

useLayoutEffect

This Hook is identical to useEffect, but it only fires after all Document Object Model (DOM) mutations. We can use it as follows:

import { useLayoutEffect } from 'react'useLayoutEffect(didUpdate)

The useLayoutEffect Hook can be used to read information from the DOM.

Use the useEffect Hook when possible, because useLayoutEffect will block visual updates and slow down your application.

Finally, we are going to take a look at the last Hook provided by React at the time of writing.
