To handle DOM updates in Vanilla JS while using async/await for fetching and displaying data from an API, you can follow this approach: Use async functions to fetch data and then update the DOM elements once the data is received.

<!-- BEGIN COPY / PASTE -->
        async function fetchDataAndUpdateDOM(url) {
            try {
                const response = await fetch(url);
                if (!response.ok) {
                    throw new Error('Network response was not ok');
                }
                const data = await response.json();
                const element = document.getElementById('data-container');
                element.textContent = JSON.stringify(data, null, 2);
            } catch (error) {
                console.error('Fetch error:', error);
            }
        }

        // Call the function with your API endpoint
        fetchDataAndUpdateDOM('https://api.example.com/data');
        <!-- END COPY / PASTE -->

Additional Comment:

Use "fetch" to retrieve data from the API and "await" to pause execution until the promise resolves.
Check the response status with "response.ok" to handle errors.
Update the DOM by selecting an element and modifying its content using "textContent".
Use "try...catch" to handle any errors during the fetch operation.
Replace 'https://api.example.com/data' with your actual API endpoint.
