CHALLENGE 3: Compile and Run
==================================

SOLUTION:

Step 1: Create src/greet.ts
----------------------------
const name: string = "Alice";
console.log(name.toUpperCase());

Step 2: Compile
---------------
npx tsc

(This generates dist/greet.js)

Step 3: Run
-----------
node dist/greet.js

Output: ALICE

EXPLANATION:
This demonstrates the complete TypeScript workflow:

1. Write TypeScript (.ts file) with type annotations
2. Compile with "tsc" (TypeScript compiler) → generates JavaScript (.js file)
3. Run the JavaScript with Node.js

WHY THIS MATTERS:
- Browsers don't understand TypeScript natively
- The TypeScript compiler converts it to plain JavaScript
- The JavaScript file is what actually runs

VARIATION:
You could also print just "Hello, [name]" instead:

const myName: string = "Bob";
console.log("Hello, " + myName);

OR use template literals (more modern):

const myName: string = "Charlie";
console.log(`Hello, ${myName}!`);

All three approaches work!

DEBUGGING TIPS:
- If "node dist/greet.js" fails, make sure:
  1. You ran "npx tsc" first (creates dist/ folder)
  2. The dist/greet.js file actually exists
  3. You're in the correct directory
