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

# Primitive types in JavaScript

JavaScript does have some basic primitive types, but what are they? 

The JavaScript code below outputs the types of four variables with various kinds of values. We'd hope for `string`, `number`, `boolean`, and `date` to be output ... but is this the case? Run the code and find out.

const name = "Bob";
console.log("Type of name:", typeof name);

const age = 30;
console.log("Type of age:", typeof age);

const cool = true;
console.log("Type of cool:", typeof cool);

const dateOfBirth = new Date(1989, 10, 5);
console.log("Type of dateOfBirth:", typeof dateOfBirth);

JavaScript

Nearly! JavaScript does have `string,` `number`, and `boolean` types, but there is no specific `date` type; instead, dates are of type `object`.

Let's play with the other primitive types available in JavaScript which are `bigint`, `null`, `undefined`, and `symbol`. Let's run the code below:

TypeScript adds a rich type system to JavaScript. Before we start to use this rich type system, we need to learn what types we have in JavaScript.

Why TypeScript?

Using basic types

Creating types

Working with generic types

Creating strongly-typed function component props
