What are some examples of coroutines in programming?

Coroutines are a powerful feature in programming that allow for cooperative multitasking. For example, in Python, you can use the 'async' and 'await' keywords to define coroutines.

Can you show me a simple Python coroutine example?

Sure! Here's a simple example:

import asyncio

async def my_coroutine():
    print('Coroutine started')
    await asyncio.sleep(1)
    print('Coroutine ended')

asyncio.run(my_coroutine())

What about coroutines in JavaScript?

In JavaScript, you can use 'async' functions as coroutines. Here's an example:

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

Are there any performance benefits to using coroutines?

Yes, coroutines can improve performance by allowing your program to handle I/O-bound tasks more efficiently, as they can pause and resume without blocking the entire thread.
