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

## Understanding React context

React context allows several components in a tree to share some data. It's more convenient than passing the data via props down the component tree.

The context is *provided* at a point in the component tree, and then all the children of the provider can access the context if they wish.

In this lesson, we will learn what context is and discover how TypeScript can infer the type for it.
