How can I use async/await in my Express application?

You can use async/await in your Express routes to handle asynchronous operations more cleanly. Just define your route handler as an async function.

Can you show me a simple example?

Sure! Here's a basic example:

app.get('/data', async (req, res) => {
    try {
        const data = await fetchData(); // Assume fetchData is an async function
        res.json(data);
    } catch (error) {
        res.status(500).send('Error fetching data');
    }
});

What happens if the async function throws an error?

If the async function throws an error, it will be caught in the catch block, allowing you to handle it gracefully.

Is there a way to handle multiple async calls?

Yes, you can use Promise.all() to handle multiple async calls concurrently. Just make sure to await the result.
