🛠️ Installation of TypeScript

📥 Step 1: Download TypeScript

To download the latest version of TypeScript, visit the official website:

Alternatively, if you have Node.js installed, you can install TypeScript globally using npm:

npm install -g typescript

✍️ Step 2: Write Your First TypeScript Program

Create a new file named first.ts and add the following code:

var message: string = "Rajesh Kumar";
console.log(message);

This will generate a first.js file in the same directory.

➡️ Run the compiled JavaScript file using Node.js:

node first.js

✅ You will see the output:
