Async Await

Summary

Syntactic sugar over Promises that lets asynchronous code read like synchronous code, using `async` functions and the `await` keyword. `async`/`await` improves readability, but developers still need to understand Promise concurrency, rejection handling, sequential versus parallel execution, and cleanup.

• 1Rewrite a `.then()` chain using `async`/`await` and `try`/`catch`. Validate your understanding by applying it in a small practical example.
• 2Fetch real data from a public API using `async`/`await`. Validate your understanding by applying it in a small practical example.
• 3Learn that `await` only pauses within its own `async` function, not the whole program.
