Typescript : How to overload a protected class constant

Question

With typescript, when defining classes with inheritance, is it possible to overload a protected constant ?

Exemple :

class A {
   static defaultProps = {
      message: ''
   }
}

class B extends A {
   static defaultProps = {
      // get defaultProps from A,
      title: ''
   }
}

I don't know if it's important that I'm working with React.

You should just extend the defaultProps prop from A class (note: the defaultProps is ˙static` so you can access that on the class not on the instance)

The following should work:

class A {
   static defaultProps = {
      message: ''
   }
}

class B extends A {
   static defaultProps = {
      ...A.defaultProps,
      title: ''
   }
}
