web.other interfaces.

The EventSource interface is web content's interface to server-sent
An EventSource instance opens a persistent connection to an HTTP
which sends events in text/event-stream format.

EventSource Events.

The FileReaderSync interface allows to read File or Blob objects
a synchronous way.

See our complete example in the article Cooperative Scheduling
Background Tasks API.

The InputDeviceCapabilities interface of the Input Device Capabilities
provides information about the physical device or a group of
devices responsible for generating input events. Events caused
the same physical input device get the same instance of this
but the converse isn't true. For example, two mice with the same
in a system may appear as a single InputDeviceCapabilities instance.

The MessageChannel interface of the Channel Messaging API allows
to create a new message channel and send data through it via
two `web.other.MessagePort` properties.

The MessagePort interface of the Channel Messaging API represents
of the two ports of a `web.other.MessageChannel`, allowing messages
be sent from one port and listening out for them arriving at
other.

MessagePort Events.

The MimeType interface provides contains information about a
type associated with a particular plugin. `NavigatorPlugins.mimeTypes`
an array of this object.

The MimeTypeArray interface returns an array of `web.other.MimeType`
each of which contains information about a supported browser
This object is returned by `NavigatorPlugins.mimeTypes`.

The NetworkInformation interface provides information about the
a device is using to communicate with the network and provides
means for scripts to be notified if the connection type changes.
NetworkInformation interfaces cannot be instantiated. It is instead
through the connection property of the `web.performance.Navigator`

A Selection object represents the range of text selected by the
or the current position of the caret. To obtain a Selection object
examination or manipulation, call `Window.getSelection()`.

TextEncoder takes a stream of code points as input and emits

– a C-like representation of strings based on typed arrays.

The Touch interface represents a single contact point on a touch-sensitive
The contact point is commonly a finger or stylus and the device
be a touchscreen or trackpad.

The UserProximityEvent indicates whether a nearby physical object
present by using the proximity sensor of a device.

The Worklet interface is a lightweight version of `Web Workers`
gives developers access to low-level parts of the rendering pipeline.
