Example of change tracking behavior after applying complex object detection

complexdetectionexample.js

var viewModel = {
    Name: ko.observable("Pete"),
    Age: ko.observable(29),
    Skills: {
        Tdd: ko.observable(true),
        Knockout: ko.observable(true),
        ChangeTracking: ko.observable(false),
    },
    Occupation: ko.observable("Developer")
};

applyChangeTracking(viewModel);

viewModel.Skills().ChangeTracking(true);

getChangesFromModel(viewModel);
/* -> { 
    "Skills": { 
        Tdd: function observable() { .... },
        Knockout: function observable() { .... },
        ChangeTracking: function observable() { .... },
    } 
} */
