It can be very useful when you want to receive some data from the server in the JSON format and show it to the user via declarative bindings.

A manual mapping example

For better understanding of the mapping concept, let's consider an example with manual mapping of JSON data to a ViewModel object. We will take a very abridged version of the library model from the previous chapters. Suppose the model contains only two properties: LibraryName and AmountOfBooks.
