React Hooks

Take note that React Hooks are still in Alpha.

Sample code

React Hooks are available for functional component which are a "replacement" for react state in class component.

Using useState() you can create an array, where the first item in the array is the state, and the second item is a function to set the state.

What makes hook really awesome is useEffect() function, because it replace 3 lifecycle hooks of react class component (componentDidMount, componentWillUnmount() & componentDidUpdate)
