What is onclick?

Onclick is an event attribute in HTML that is used to trigger a specific action when a user clicks on an element, such as a button or a link. This action can be anything from opening a new webpage, submitting a form, or displaying a message. The onclick attribute is commonly used in conjunction with JavaScript to create interactive and dynamic web pages.
