Encapsulation of Requests:?

Q: Encapsulation of Requests:?

Short answer: The command (in this case, AddTextCommand) encapsulates the request to add text to the document as an object. This allows for parameterization of the command with different requests (e.g., adding different text) while decoupling the sender (the TextEditor) from the receiver (Document). Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
