A reference to an object owned by the Chakra garbage collector.

typedef void *JsRef;

A Chakra runtime will automatically track JsRef references as long as they are stored in local variables or in parameters (i.e. on the stack). Storing a JsRef somewhere other than on the stack requires calling JsAddRef and JsRelease to manage the lifetime of the object, otherwise the garbage collector may free the object while it is still in use.
