What is the "state" of a Display Form and how can I use it?

I see the .state used in expressions to get the value of elements in a form.

In the documentation, I find only the following:

 

state : A form's state output gives you access to the individual inputs that the user entered in the form.

  Hi Nico,

   

  The .state provides access the Display Form's elements.

   

  For example, if you have a Display Form with a Check Group in it, if you wanted to access the value of one of the Check Boxes within it, you would use this syntax: =$CheckGroupForm.state.CheckGroup.items[0].checked

   

  CheckGroupForm is the Display Form activity and CheckGroup is the ID of the Check Group form element that I have configured within it.

   

  Thanks, Stefan

  Yes, I know this. But it raises the question why it is not just

  =$CheckGroupForm.CheckGroup.items[0].checked

  Is it related to the state concept in React?
