How can I implement async code in Python and JavaScript?

In Python, you can use the asyncio library to write asynchronous code. In JavaScript, you can use async and await keywords.

Can you show me a simple example in both languages?

Sure! In Python:

import asyncio

async def main():
    print('Hello')
    await asyncio.sleep(1)
    print('World')

asyncio.run(main())

And in JavaScript:

async function main() {
    console.log('Hello');
    await new Promise(resolve => setTimeout(resolve, 1000));
    console.log('World');
}

main();

What are the benefits of using async programming?

Async programming allows for non-blocking operations, which can improve performance, especially in I/O-bound tasks.
