What are async functions in programming?

Async functions are a way to handle asynchronous operations in programming, allowing code to run without blocking.

Can you give me an example of how to use an async function?

Sure! Here's a simple example in JavaScript:

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

This function fetches data from an API without blocking the execution of other code.

What is the difference between async and synchronous functions?

Synchronous functions execute in sequence, blocking the next operation until the current one completes. Async functions allow other operations to run while waiting for a task to complete.

Are there any drawbacks to using async functions?

Yes, async functions can make error handling more complex and may lead to unhandled promise rejections if not managed properly.
