A "Click Event" refers to an action that occurs when a user presses a mouse button over a specific element on a computer screen, such as a button or a link. This action is commonly used in web development to trigger various functions, such as opening a new page, submitting a form, or displaying additional information. In programming, particularly in languages like JavaScript, click events are often handled using event listeners. These listeners wait for the click action and then execute a predefined function, allowing developers to create interactive and dynamic user experiences on websites and applications.
