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.

If you’re looking for the updated version of this course featuring V16, please visit The Road to React: The one with Hooks.

The Road to learn React by Robin Wieruch is a must read. Clean and concise for React and JavaScript.

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

# Introduction to Enzyme
[Enzyme](https://github.com/airbnb/enzyme) is a testing utility by Airbnb to assert, manipulate, and traverse React components. It is used to conduct unit tests to complement snapshot tests in React. First we have to install it along with its extension, since it doesn't come with *create-react-app*.

# Installing Enzyme

npm install --save-dev enzyme react-addons-test-utils enzyme-adapter-react-16

Second, we include it in the test setup and we initialize its adapter.


import React from 'react';
import ReactDOM from 'react-dom';
import renderer from 'react-test-renderer';
import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
import App, { Search, Button, Table } from './App';

Enzyme.configure({ adapter: new Adapter() });


Now you can write your first unit test in the Table "describe"-block. You will use `shallow()` to render your component and assert that the Table was passed two items. The assertion simply checks if the element has two elements with the class `table-row`.

In this lesson, we'll discuss unit testing in React using a testing utility called Enzyme.
