RTCDataChannel.bufferedAmount - Web APIs
the read-only rtcdatachannel property bufferedamount returns the number of bytes of data currently queued to be sent over the data channel.
...this only includes data buffered by the user agent itself; it doesn't include any framing overhead or buffering done by the operating system or network hardware.
...however, even after closing the channel, attempts to send messages continue to add to the bufferedamount value, even though the messages are neither sent nor buffered.

RTCDataChannel.bufferedAmountLowThreshold - Web APIs

Media buffering, seeking, and time ranges - Developer guides
sometimes it's useful to know how much <audio> or <video> has downloaded or is playable without delay — a good example of this is the buffered progress bar of an audio or video player.
... buffered the buffered attribute will tell us which parts of the media has been downloaded.
... this will work with <audio> or <video>; for now let's consider a simple audio example: <audio id="my-audio" controls src="music.mp3"> </audio> we can access these attributes like so: var myaudio = document.getelementbyid('my-audio'); var bufferedtimeranges = myaudio.buffered; timeranges object timeranges are a series of non-overlapping ranges of time, with start and stop times.

... mybufferedtimeranges = myaudio.buffered; seekable the seekable property informs you of whether you can jump directly to that part of the media without further buffering.
