Answer 1

C and C++ are indeed commonly used in the creation of operating systems, because of their low-level programming features. Java with Android Studio and C# with Xamarin are popular for Android apps. Concerning desktop development on Windows C# is often used. Java is a great choice for multiplatform apps.

Answer 2

For making an operating system you usually start with asm and later on, when the core is finished, use C or C++. Javascript is definitely not used for creating an os.
