This API is experimental and may have breaking changes later.

Requires an active script context. If object is not a Proxy object the target and handler parameters are not touched. If nullptr is supplied for target or handler the function returns after setting the isProxy value. If the object is a revoked Proxy target and handler are set to JS_INVALID_REFERENCE. If it is a Proxy object that has not been revoked target and handler are set to the the object's target and handler.
