Output Format
## Overview
This code implements a data fetching utility...
## Line-by-Line Breakdown
### Line 1: Function Declaration
`async function fetchData(url)`
- `async` allows the function to use await
- `url` parameter expects a string URL
### Line 2: Fetch Call
`const response = await fetch(url)`
- `fetch()` makes an HTTP GET request
- `await` pauses until the request completes
### Line 3: Return JSON
`return response.json()`
- Parses the response body as JSON
- Also returns a Promise
## Summary
This is an async utility for fetching JSON data from APIs.
