If you’re working with a legacy React codebase, then this course will prove useful. React has seen a great deal of change over the years, but there might be situations where you have to work with an older version.

In this course, you will learn the fundamentals of V15 React. You will learn how to work with an API, how to organize and test your code as well as how to give your React app state. Throughout this course, you will have hands-on experience building a fully functional Hacker News App. By the end of this course, you will be prepared to build your own applications and have something to showcase in your portfolio.

This is one of the most well-written & informative coding books I’ve ever worked through. A solid React & ES6 introduction.

The Road to Learn React by Robin Wieruch is such an awesome book! Most of what I learned about React and even ES6 was through it!

I recommend this to any student or professional interested in learning react basics to advanced level. I have 17 years of experience in web and desktop app development, and before reading this I was having trouble in learning react. It works like magic.

The Road to React: The One with Class Components

# What does 'Lifting State' mean?
Only the App component is a stateful ES6 component in your application. It handles a lot of application state and logic in its class methods. Moreover, we pass a lot of properties to the Table component, most of which are only used in there. It's not important that the App component knows about them, so the sort functionality could be moved into the Table component.

Moving a sub-state from one component to another is known as lifting state. We want to move state that isn't used in the App component into the Table component, down from parent to child component. To deal with state and class methods in the Table component, it has to become an ES6 class component. 

# Refactoring the Table component
Refactoring from functional stateless components to ES6 class components is simple.
Your Table component as a functional stateless component:

We have already covered the basics of state management in React in the previous chapters by using React's local state, so this chapter will dig a bit deeper. In this lesson, we'll learn what lifting state in React is and how it is used.
