Introduction to TypeScript and React

In this tutorial, we will learn about using TypeScript with React.

Step 1: Create a New React Project

Create a new React project using create-react-app by running the following command in your terminal:

npx create-react-app my-app --template typescript

Step 2: Define a Type-Safe Component

Create a new file called Hello.tsx and add the following code:

import * as React from 'react';
interface Props {
  name: string;
}
const Hello: React.FC<Props> = ({ name }) => {
  return <div>Hello, {name}!</div>;
};

This code defines a type-safe Hello component.

Step 3: Use the Component

Create a new file called App.tsx and add the following code:

import * as React from 'react';
import Hello from './Hello';
const App: React.FC = () => {
  return <Hello name='Alice' />;
};

This code uses the Hello component.
