Question

Is there any super set or language similar to javascript that provides a more classical c++/java/c#-like OO System. But can be used with HTML-5 and DOM and has a cross-platform implementation?

Answer 1

Yes, it’s called JavaScript. There are some good articles about OOP around

var Parent = {
  method: function () {
    ...
  }
}

var Child = Object.create(Parent, {
  childMethod: { value: function () {
    ...
  } }
})

Any attempt to emulate a class system in JavaScript is a waste of time and ends up writing bloated / unreadable / unmaintainable code.

If the above is too ugly, consider using an extend function
