What event is needed if we perform logic over the result such as checking if it is empty?

The event that is required when performing logic over the result, such as checking if it is empty, is the "After Fetch" event. This event occurs after data has been retrieved from a source, which allows developers to implement logic based on the fetched data.

When using the "After Fetch" event, one can inspect the data collected, assess whether the result set is empty or contains valid entries, and execute additional logic accordingly. For instance, if the fetched result is empty, you can handle that scenario specifically (like displaying a message to the user). This event essentially serves as a hook for executing code right after data retrieval, ensuring that actions are taken based on the actual results.

The other events, such as "Ready," "Render," and "Destroy," serve different purposes in the application lifecycle. "Ready" is used to initialize components before they become visible, "Render" is associated with displaying components on the screen, and "Destroy" handles cleanup before an object is removed. These do not provide the appropriate context needed for handling the results of data fetching.
