How To Make A Calculator Using HTML CSS And JavaScript

This illustration uses HTML for the structure and styling, and JavaScript for the calculator logic. The appendToDisplay function is used to append values to the display, the clearDisplay function is used to clear the display, and the calculateResult function evaluates the expression in the display and updates the display with the result. Please note that using eval to evaluate expressions can have security implications, so make sure to sanitize and validate input if you plan to use this in a production environment.
