Question

The video and the audio belong to the _________

(a) Timers and error handlers

(b) API-Specific events

(c) State change events

(d) User interface events

I had been asked this question during an online interview.

The query is from Mouse Events topic in section Document Object Model and Event Handling in Javascript of JavaScript

Answer 1

Right answer is (b) API-Specific events

To explain I would say: The HTML5 video and audio elements define a long list of associated event types such as “waiting”, “playing”, “seeking”, “volumechange”, and so on. These events are usually only of interest to web apps that want to define custom controls for video or audio playback.
