How to tell if a element is currently playing?

There is not a specific attribute that will reveal whether a MediaElement is currently playing. However, you can deduce this from the state of the other attributes. If:

• currentTime is greater than zero, and
• paused is false, and
• ended is false

then the element is currently playing.

You may also need to check readyState to see if the media stopped due to errors. Maybe something like that:

const isVideoPlaying = video => !!(video.currentTime > 0 && !video.paused && !video.ended && video.readyState > 2);
