Well yes, the JavaScript is not converted into Objective C, it is bundled into the app bundle that you submit to the App Store. I guess it depends on whether you consider the ultimate bundling of the application to be compiling.
Anyway, the point is that it doesn't run in a WebView. The JavaScript is executed by JavaScriptCore.
Irregardless, "daylight saving time" is the only cromulent term, we must stop embiggening peoples' vocabularies with alot of fake words!
