939909 - Internal Promise implementation should not use Optional<JS::Handle<JS::Value> > forms

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Nikhil Marathe [:nsm] (No longer reading bugmail, please needinfo?)]

JS::Value already encodes the semantics of optional, this is redundant, especially in internal methods that are not wired to WebIDL. bz eventually plans to get rid of the |optional any| webidl form too.

  JS::Rooted<JS::Value> value(aCx, args.get(0));

Or even more simply, just pass args.get(0) in the places where "value" is passed right now and remove all this code.

Apart from that, looks great.  Thank you for doing this!
