Path _path

I don't understand why do we have: private readonly Path _path Can someone please explain! And also, why when we create "Invader" constructor we write: Invader(Path path) ?

Let's break that down:

  • private :point_left: this will only be available to code inside the class
  •     readonly :point_left: after the instance is created, it cannot be changed
  •         Path :point_left: it is an item of type "Path"
  •             _path :point_left: and it's name is "_path"

And when you create an instance, you pass the Path to the constructor, which is why it has that parameter. Inside the constructor, the field value is set ("_path = path;"), and it will be permanent for the life of the instance.

does it read as private readonly Path _path' because we are using _path as the attribute name and the argument name from the constructor?

would private readonly Path _path = _path; technically work (is what's going on under the hood) aswell?
