JavaScript is event-driven because it responds to events that occur on a web page, like user actions such as clicking a button or scrolling on the page. Then when an event is triggered JavaScript will do a specific set of instructions or functions, which are created by the programmer to respond to the event that user engaged in. JavaScript can handle multiple events at the same time and will respond to user interactions without blocking the use of other code. For example, when a user clicks a button on a web page, an event is triggered then the JavaScript code can be used to respond to that event by updating the content on the page being interacted with. This change can be a pop up that occurs or even the style could be different. Overall, the event-driven architecture of JavaScript allows it to respond to a wide range of events and provide a more interactive and engaging user experience on web pages without interrupting other code as well.

Hi Ryan, thanks for your post! This was a really easy-to-understand description of what event-driven means. It’s helpful to think about how this looks from the user end, like clicking a button. It’s also helpful to think about how the code doesn’t completely stop running just because an event is triggered. I think you’re right, this feature of JavaScript definitely allows for more engaging UX.
