I have to agree - if anything there is a greater move away from JavaScript towards native platforms, although I think that C# via Unity and Xamarin.iOS/Xamarin.Android is gaining significant popularity. C++ does technically work on both iOS and Android, but I think its use outside of games is fairly small - Google has bold text on the NDK download page saying it won't be useful for many applications and Xcode's support isn't anywhere near as good as its support for Objective-C.
