A helper function that given a value ensure that the value is returned as an observable. If the value is already an observable it is simply returned if not a new observable is created wrapping that value. This is helpful when you want your code to use an observable but you want the developer to be able to pass a value or and observable value.

self.value = ko.asObservable(possibleObservableValue);


Same as asObservable but for observableArray.

self.array = ko.asObservableArray(possibleObservableArray);
