As I uderstood, here, in the spec it states that if target is "function", then trap "apply" is available, to catch function invocations http://wiki.ecmascript.org/doku.php?id=harmony:virtual_object_api
And that's how it behaves in Forefox -- it just ignores "apply" trap if target object is not a function. 2016-03-02 14:55 GMT+02:00 Caitlin Potter <[email protected]>: > What exactly do you mean by “restricted to functions only”? > > On Mar 2, 2016, at 7:21 AM, Олег Галабурда <[email protected]> wrote: > > Hi! > > I'm currently working on project that allows to manipulate objects passed > from Worker. > https://github.com/burdiuz/js-worker-interface > > It creates wrapper objects that record actions applied to this object and > send commands to Worker.
