Gain insights into integrating TypeScript with React to improve productivity. Learn about strongly-typed props, state, and events, and set up projects using Create React App, Webpack, and Babel.

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

# An `any` type refresher

We learned from a [previous lesson](https://www.educative.io/pageeditor/4619705736232960/4884662000287744/5689667292758016) that the `any` type could be used when we are unsure of the type of value. The problem with `any` is that no type checks will be carried out on values of type `any`. 

What if there was a type like `any` that can be used for values we don't know but was also type-safe? This is what the `unknown` type is!

In this lesson, we will learn about the 'unknown' type; it is similar to the 'any' type but is type-safe.
