Cu.import("resource://gre/modules/NewTabUtils.jsm"); var { links: gLinks, allPages: gAllPages, linkChecker: gLinkChecker, pinnedLinks: gPinnedLinks, blockedLinks: gBlockedLinks, gridPrefs: gGridPrefs } = NewTabUtils; and the scipt of NewTabUtils.jsm is /** * Singleton that provides the public API of this JSM. */ this.NewTabUtils = { a_Property_is_here: false, Some_Method_A: function Some_Method_A() { } Some_Method_B: function Some_Method_A() { } And_so_on: function And_so_on() { } links: Links, allPages: AllPages, linkChecker: LinkChecker, pinnedLinks: PinnedLinks, blockedLinks: BlockedLinks, gridPrefs: GridPrefs, placesProvider: PlacesProvider, activityStreamLinks: ActivityStreamLinks, activityStreamProvider: ActivityStreamProvider }; What does the part "var{properties}=NewTabUtils;" mean? I understand if that's "NewTabUtils={properties};" And another minor question is about the second script, in the Class-like JS methods, properties are asigned at bottom of the script, also bottom of the file. I guess that's because it is easy to read, but not sure the reason. Would somebody know these questions? thanks.
