Determine the type of class or instance from the constructor function

How can you determine the class type or instance type using a constructor function?

EDIT: Given only the prototype, how can you identify the class type? Refer to the example with decorators.

Class User {}

// It's really disappointing that I have to do this
User.prototype/* Object */.constructor/* Function */

Example using a property decorator:

// This is my code
// I struggle to retrieve the class/instance type from T...
const Prop = <T>({ constructor }: T) => {}

// User's code
class User {
  @Prop
  photos
}

Thank you

Experiment with the InstanceType method:

const CarInstance = InstanceType<CarModel>;
