Code Block
titleJavaScript Bridge implementation
The JS Bridge consists of 2 parts:
    - execution backend (written in C++)
    - client interface to execution backend (this one)

  Each part consists of 2 layers:
   - object interface (methods calls)
   - general messaging (serialized messages)

  Each method call JS => C++ is serialized into JSON, trasfered via IPC,
  received on another side, mapped into the corresponding method call.
  So, the route is:

  C++                        JS
  -------------------       -------------------
  object interface  <      < object interface
  ------------------ |     |-------------------
  general messaging  |     | general messaging
  ------------------ |     |-------------------
  IPC                 <===<  IPC

  Responses and events are transferred in opposite direction (C++ => JS)
