Angular has 1 form with 40 properties. How to find a misspelled property name?

Question

JavaScript

It seems that according to the initial data, everything is trivial : it is assumed that their names may change. Is there a ready-made way so that the program can check itself that when reading some parameter is not present or when writing, too, that some parameter is not present and issue a warning? There are no browser restrictions. PS Do not offer recording functions, because. property names are written to ng-model. Those. it is necessary that already at the moment of model initialization it could be understood that something in the interface is wrong.
