How can I use the Fetch API for advanced data handling?

You can use the Fetch API to handle complex data by utilizing features like Promises, async/await, and custom headers.

Can you show me an example of using async/await with Fetch?

Sure! Here's a simple example:

async function fetchData(url) {
    try {
        const response = await fetch(url);
        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error('Error fetching data:', error);
    }
}

This function fetches data from a given URL and logs it.

What about handling errors in Fetch?

You can handle errors by checking the response status. If it's not in the 200 range, throw an error. Here's an example:

async function fetchData(url) {
    const response = await fetch(url);
    if (!response.ok) {
        throw new Error('Network response was not ok ' + response.statusText);
    }
    return await response.json();
}
