If you are a React developer and want to build your React apps faster and more robustly, this course is for you. Learn to integrate TypeScript with React, boost your productivity, and create apps that are easier to maintain.

In this course, you will learn how to utilize TypeScript’s sophisticated type system to make React development faster and your code more readable. You will learn how to create component props, state, and events that are strongly-typed, allowing you to quickly understand what you can pass and helping you avoid mistakes.

Lastly, you will set up React projects with TypeScript. First, you will learn how to do this with the Create React App tool, then how to create a React and TypeScript project with Webpack and Babel.

Using TypeScript with React

## Running tests

The `App` component has an example test in the `App.test.tsx`, which checks that the component renders without crashing. This test is the [**Jest**](https://jestjs.io/) test which we will learn about later in this course.

The tests can be run in the Terminal by the following npm command:

```shell
npm test
```

The tests will then be run and the results output in the Terminal:

With the project we have set up in the previous lessons, we are now going to learn how to run tests within the project and how to create a production-ready build.
