The ByteLengthQueuingStrategy interface of the the Streams API
a built-in byte length queuing strategy that can be used when
streams.

The ConstrainBoolean dictionary is used to specify a constraint
a property whose value is a Boolean value. You can specify an
value which must be matched, an ideal value that should be matched
at all possible, and a fallback value to attempt to match once
more specific constraints have been applied.

The ConstrainDOMString dictionary is used to specify a constraint
a property whose value is a string. It allows you to specify
or more exact string values from which one must be the parameter's
or a set of ideal values which should be used if possible. You
also specify a single string (or an array of strings) which the
agent will do its best to match once all more stringent constraints
been applied.

The ConstrainLong type is used to specify a constraint for a
whose value is an integral number. It extends the `web.streams.LongRange`
(which provides the ability to specify a permitted range of property
to also support an exact value and/or an ideal value the property
take on. In addition, you can specify the value as a simple long
value, in which case the user agent does its best to match the
once all other more stringent constraints are met.

web.streams interfaces.

The CountQueuingStrategy interface of the the Streams API provides
built-in byte length queuing strategy that can be used when constructing

The DoubleRange dictionary is used to define a range of permitted
floating-point values for a property, with either or both a maximum
minimum value specified. The `web.rtc.ConstrainDouble` dictionary
based on this, augmenting it to support exact and ideal values
well.

The LongRange dictionary is used to define a range of permitted
values for a property, with either or both a maximum and minimum
specified. The `ConstrainLongRange` dictionary is based on this,
it to support exact and ideal values as well.

The MediaStream interface represents a stream of media content.
stream consists of several tracks such as video or audio tracks.
track is specified as an instance of `web.video.MediaStreamTrack`.

MediaStream Events.

The MediaStreamTrackEvent interface represents events which indicate
a `web.streams.MediaStream` has had tracks added to or removed
the stream through calls to Media Stream API methods. These events
sent to the stream when these changes occur.

The MediaTrackConstraints dictionary is used to describe a set
capabilities and the value or values each can take on. A constraints
is passed into `applyConstraints()` to allow a script to establish
set of exact (required) values or ranges and/or preferred values
ranges of values for the track, and the most recently-requested
of custom constraints can be retrieved by calling `getConstraints()`.

The MediaTrackSupportedConstraints dictionary establishes the
of constrainable properties recognized by the user agent or browser
its implementation of the `web.video.MediaStreamTrack` object.
object conforming to MediaTrackSupportedConstraints is returned
`MediaDevices.getSupportedConstraints()`.

The TransformStream interface of the Streams API represents a
of transformable data.

The WritableStream interface of the the Streams API provides
standard abstraction for writing streaming data to a destination,
as a sink. This object comes with built-in backpressure and queuing.

The WritableStreamDefaultWriter interface of the the Streams
is the object returned by `WritableStream.getWriter()` and once
locks the < writer to the WritableStream ensuring that no other
can write to the underlying sink.
