 **NOTE:** the `getVersion` handler call on **/version** endpoint. We actually need to implement it now.
 If we made some mistakes in step implementations, we will know about it when we run the tests.
 
+Though, we could also improve our **JSON** comparison function to range through the interfaces and
+match their types and values.

 In case if some router is used, you may search the handler based on the endpoint. Current example
 uses a standard http package.
