What are the differences between async/await and callbacks in Express?

What are the differences between async/await and callbacks in Express?

Async/await provides a cleaner syntax and better error handling compared to callbacks, which can lead to callback hell.

Can you give me an example of using async/await in an Express route?

Sure! Here's a simple example:

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

What about error handling with callbacks?

With callbacks, you typically pass an error as the first argument. It can lead to nested structures, making it harder to read.

Which one is recommended for new projects?

Async/await is generally recommended for new projects due to its readability and ease of use.
