JavaScript functions and click events are implemented to handle user input, manage calculations, and display results dynamically. The calculator includes essential features such as clearing the display, deleting digits using the backspace button, decimal number input, and basic error handling for division by zero. Tailwind CSS is used to create the layout and styling, while Font Awesome provides icons to enhance the visual design.
This project demonstrates practical knowledge of HTML, Tailwind CSS, JavaScript, event handling, conditional statements, and DOM interaction. It helped improve my understanding of frontend development, calculation logic, and interactive user interface design. The application can be further enhanced with keyboard support, calculation history, and additional mathematical functions.
