+##### `isolate.referenceCount` *[number]*
+Returns the total count of active `Reference` instances that belong to this isolate. Note that in
+certain cases many `Reference` instances in JavaScript will point to the same underlying reference
+handle, in which case this number will only reflect the underlying reference handle. This happens
+when you transfer a `Reference` instance via some method which accepts transferable values. This
+will also include underlying reference handles created by isolated-vm like `Script` or `Context`
+objects.
