The Transferable interface represents an object that can be transfered between different execution contexts, like the main thread and Web workers.
This is an abstract interface and there is no object of this type. This interface does not define any method or property; it is merely a tag indicating objects that can be used in specific conditions, such as being transfered to a Worker using the Worker.postMessage() method.
Note: The Transferable interface technically no longer exists. The functionality of Transferable objects still exists, however, but is implemented at a more fundamental level (technically speaking, using the [Transferable] WebIDL extended attribute).
The ArrayBuffer, MessagePort, ImageBitmap and OffscreenCanvas types implement this interface.
