When you import an Apex method into your LWC JavaScript file, it allows you to invoke that method as a promise. This is vital as it aligns with the asynchronous nature of web programming, enabling the LWC to handle server responses efficiently, including success and error handling appropriately.

In contrast, directly referencing the Apex method in an HTML template would not function because LWC templates do not support direct calls to server-side code for security and encapsulation reasons. Similarly, simply creating an Apex controller class does not automatically connect it to the LWC; the methods must still be appropriately imported and called. Attaching the method to a button click event may lead to invoking the method but does not constitute a method of calling the Apex method; rather, it’s a means of triggering the appropriate JavaScript function where the method call takes place.

Thus, by using the import statement and invoking the method in a JavaScript function, developers
