        name: ko.Observable<string>;
        children: ko.ObservableArray<MyChildModel>;
    }
    
    class MyChildModel {
        id: ko.Observable<number>;
        name: ko.Observable<string>;
        nameLength: ko.Computed<number>;
        
        constructor(data) {
            mapping.fromJS(data, {}, this);
            this.nameLength = ko.pureComputed(() => this.name().length, this);
        }
    }
    
    const data = {
        name: 'Scott',
        children: [
            { id : 1, name : 'Alice' }
        ]
    };
    
    const options: mapping.Options = {
        ignore: ["propertyToIgnore", "alsoIgnoreThis"],
        include: ["propertyToInclude", "alsoIncludeThis"],
        copy: ["propertyToCopy"],
        observe: ["propertyToObserve"],
        
        "name": {
            update: options => options.data + " foo!"
        },
        "children": {
            key: data => ko.utils.unwrapObservable(data.id),
            create: options => new MyChildModel(options.data)
        }
    };
    
    const viewModel = mapping.fromJS<ViewModel>(data, options);
    
    // Every time data is received from the server:
    mapping.fromJS(data, options, viewModel);
    
    const unmapped = mapping.toJS(viewModel);
})();
