   External Binding
   ~~~~~~~~~~~~~~~
  
positive.code: FormData
  ~~~~~~~~
  
  Above, we considered a method allowing to read values and update from inputs. The flaw of this is a need of read input one-by-one and disability of files loading. FormData attended to solve this disadvantages.
  
  In the difference of `property`, FormData works with form tag, not with input tag.

  -----------------------------------
  
  Render is called for each new state. Important to understand that render produces a full DOM for every call. It does not mean that client receives a new page every time. Korolev makes a diff between current and latest DOM. Only changes will be sent to the client.
  
  `Render[S]` is a type alias to `PartialFunction[S, VDom]` where `S` is a type of your state.
  
  Transitions
  ~~~~~~~~~~~
  
  Transition is a function that applies to current state and produces a new state. Consider a transition which adds new friend to the friends list.
