📘 Day 36 — TypeScript with React: Benefits & Basics

📘 Day 36 — TypeScript with React: Benefits & Basics

TypeScript adds strong typing to JavaScript, making React applications safer, more predictable, and easier to maintain. It helps catch errors early during development.

🔹 Setting Up React with TypeScript

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

This creates a new React project with TypeScript support out of the box.

🔸 Typing Props and State

import React, { useState } from "react";

type UserProps = {
  name: string;
  age: number;
};

function User({ name, age }: UserProps) {
  return <h3>{name} is {age} years old.</h3>;
}

function App() {
  const [count, setCount] = useState<number>(0);
  return (
    <div>
      <User name="Rahul" age={22} />
      <button onClick={() => setCount(count + 1)}>Clicked {count} times</button>
    </div>
  );
}

export default App;

💡 Advantages of TypeScript

  • Type safety reduces runtime errors.
  • Better IntelliSense and autocompletion in editors.
  • Improved code readability and maintainability.
