Revision 538977 of Transferable

<p>{{ DomRef() }}</p>
<p>The <code><strong>Transferable</strong></code> interface represents an object that can be transfered between different execution contexts, like the main thread and Web workers.</p>
<p>This is an abstract interface and there isn't any object of this type. It also doesn't define any method or property: it is merely a tag indicating objects that can be used in specific conditions, like to be transfered to a {{domxref("Worker")}} using the {{domxref("Worker.postMessage()")}} method.</p>
<p>The {{domxref("ArrayBuffer")}} and {{domxref("MessagePort")}} implement it.</p>
