?What are the main components needed to build a calculator using JavaScript

To build a calculator, you need three main components: HTML for the structure (buttons and display), CSS for styling, and JavaScript to handle logic such as input processing, operations, and event handling.

?How does JavaScript handle button clicks in a calculator project

JavaScript uses event listeners (like addEventListener('click', ...)) to detect when a user clicks a button. It then processes the button value, updates the display, and performs calculations as needed.
