What are JavaScript events?

JavaScript events are actions or occurrences that happen in a web browser, typically triggered by user interactions or the browser itself. These events can include actions like clicking a button, moving the mouse, pressing a key, submitting a form, or even the page finishing loading. JavaScript allows developers to attach event listeners to these events, enabling them to respond to and handle these actions by executing specified code or functions. Events are fundamental for creating interactive and responsive web applications.
