What are some real-world examples of async functions?

Async functions are used in various applications, such as web development for handling API calls without blocking the UI.

Can you give me a specific example in JavaScript?

Sure! In JavaScript, you can use async/await to fetch data from an API like this:

async function fetchData() {
  const response = await fetch('https://api.example.com/data');
  const data = await response.json();
  console.log(data);
}

What about in Python?

In Python, you can use the asyncio library. Here's an example:

import asyncio

async def fetch_data():
    await asyncio.sleep(1)  # Simulate a network delay
    return 'Data fetched'

asyncio.run(fetch_data())

Are there any downsides to using async functions?

Yes, async functions can add complexity to your code and may lead to harder-to-debug issues if not managed properly.
