Question 1 of 30

A developer is building an interactive dashboard using JavaScript. They have a button that, when clicked, initiates a process to fetch complex configuration data from a remote server. After the data is fetched, the dashboard\'s layout needs to be dynamically updated based on this configuration. The developer wants to provide immediate visual feedback to the user that the process has started, but also ensure the layout update is robust and doesn\'t cause rendering artifacts. Which of the following approaches best balances immediate user feedback with stable UI updates in this asynchronous scenario?

Initiate the data fetch, and immediately update a status indicator on the page, then update the dashboard layout within the `.then()` block of the fetch Promise.
Initiate the data fetch and, while it's in progress, use `setInterval` to repeatedly check for data availability and update the layout when it's ready.
Initiate the data fetch and immediately attempt to update the dashboard layout with a default structure, assuming the fetched data will overwrite it later.
Use `async/await` to fetch the data, and directly update the dashboard layout immediately after the `await` keyword, before any error handling for the fetch operation.
