I don't think there's anything inherently event-based in JavaScript the language, it's just how the browser API works. You can just as easily write busy loops.
Sure, but that’s not the point here. With that logic, nothing is truly event-based if you can conceivably use it other ways. JavaScript was designed to interface with the DOM and had to support certain flows which is why I classify it inherently event based even if that does not meet technical requirements to call it so.
