Learn React hooks, lazy, and memo API

React 16.8.1 was just released, and hooks are finally stable! If you have literally 12 minutes to spare, you can learn how to use hooks (useState, useEffect and useMemo) as well as brand new React features such as React.lazy and React.memo.
Enjoy!

• Add state to functional React component with useState hook without introducing a class
• Handle multiple state values when using useState React hook
• Use React useEffect hook to see how many times component mounts and unmounts
• Optimize expensive operations with React useMemo hook
• Use React.lazy to do code-splitting with React Suspense
• Use React.memo to avoid unnecessary re-renders in React functional components
