I'm having some difficulties with nested destructuring in combination with typescript and default values.

I have the following properties bound on my window object:

serverconfig : {
  Version: {
    MajorVersionNr,
    MinorVersionNr,
    HotFixVersionNr,
    AdditionalComment,
  }
}

I would like to add typing with javascript (it are all strings) + destructure all the properties + assign a default object value to serverConfig for when it is undefined.

Before using typescript I simple did this:

const { serverConfig = {} } = window;
const { Version = {} } = serverConfig;
const { MajorVersionNr, MinorVersionNr, HotFixVersionNr, AdditionalCommen } = Version;
