📘 Concept Overview

JavaScript is single-threaded, but asynchronous operations let you do multiple tasks (like fetching data, waiting for APIs, timers, etc.) without blocking the main thread.

You’ll focus today on:

• Promises
• async/await
• Fetching data from multiple APIs
• Handling responses + errors gracefully
