You are debugging a JavaScript application and notice that the call stack refers to an anonymous function, making it difficult to trace the error. What could you do to make future debugging easier without altering the function's behavior or structure significantly?

To make future debugging easier without altering the function's behavior significantly, you can convert the anonymous function into a named one. Giving a function a meaningful name can help you identify it more easily in the call stack and error messages, making debugging less challenging. Renaming the function doesn't alter its behavior or structure but enhances code readability and maintainability.
