+Gets the current value or throws an exception.
+Value is frozen after `onCompleted` is called.
+After `onError` is called always throws the specified exception.
+An exception is always thrown after `dispose` is called.
+
+#### Returns
+*(Mixed)*: The initial `value` passed to the constructor until `onNext` is called; after which, the last value passed to `onNext`.
+
+#### Example
+```js
+var subject = new Rx.BehaviorSubject(56);
+
+console.log('Value is: ' + subject.getValue());
+
+// => Value is: 56
+
+subject.onNext(42);
+
+console.log('Value is: ' + subject.getValue());
+
+// => Value is: 42
+
+subject.onCompleted();
+
+subject.onNext(100);
+
+console.log('Value is frozen: ' + subject.getValue());
+
+// => Value is frozen: 42
+
+subject.dispose();
+
+try {
+    subject.getValue();
+} catch (e) {
