                         Improve UI:

                        o  Highlight operator buttons when selected.

                        o  Animate buttons on click.

                         Error Handling:
                        o  Display error messages for invalid inputs (e.g., division by zero).

                      Key Takeaways:

                         Event Listeners handle user interactions, making the app responsive.

                         Variables and Conditionals process and store user input for calculations.

                         User Interface Design enhances usability and experience in app development.

                      Happy Coding!
