What are some examples of asynchronous code?

Can you show me some examples of asynchronous code?

Sure! Asynchronous code allows tasks to run concurrently. Here's a simple example in JavaScript using async/await:

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

What about using promises instead of async/await?

Absolutely! Here's how you can do it with promises:

function fetchData() {
    fetch('https://api.example.com/data')
        .then(response => response.json())
        .then(data => console.log(data))
        .catch(error => console.error('Error:', error));
}
fetchData();

Can you explain the difference between async/await and promises?

Certainly! Async/await is syntactic sugar over promises, making asynchronous code easier to read and write. With async/await, you can write code that looks synchronous, while still being non-blocking.

Are there examples in Python?

Yes! In Python, you can use the asyncio library. Here's a simple example:

import asyncio

async def fetch_data():
    await asyncio.sleep(1)  # Simulate a network call
    print('Data fetched!')

asyncio.run(fetch_data())
