javascript – Do I have trouble about the "abort" or "onabort" event for what it serves?

I have already viewed all the website on which I searched for help on Google in Youtube. I 've already left my doubt on other question sites, but I can never find a concrete example of what it' s used for and they always talk about the same thing as what I do. they serve when the video is interrupted. What is this example? Is this an easy answer to understand? but whoever can help me is grateful.
