What is async programming and how can I use it in my code?

Async programming allows your code to run tasks concurrently, improving efficiency. You can use it with promises and async/await.

Can you show me a simple example of async/await in JavaScript?

Sure! Here's a basic example:

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

What happens if I don't use await with a promise?

If you don't use await, the promise will execute asynchronously, but your code won't wait for it to complete, which may lead to unexpected results.

Are there any downsides to using async programming?

Yes, async programming can make debugging more complex and may lead to callback hell if not managed properly.
