Another question popped in my head while reading your answer. Returns an observable sequence that is the result of invoking the selector on a connectable observable sequence that shares a single subscription to the underlying sequence containing only the last notification. I would probably prefer Variable over BehaviorSubject because of the mentioned compile time guarantees. (Defined by, Overloaded. Filters the elements of an observable sequence based on a predicate by incorporating the element's index. Projects each element of an observable sequence into a new form with the specified source and selector. Returns the only element of an observable sequence that matches the predicate and throws an exception if there is not exactly one element in the observable sequence. (Defined by, Overloaded. Creates a dictionary from an observable sequence according to a specified key selector function, and a comparer. (Defined by, Matches when both observable sequences have an available value. An example with no subscribe, bind, drive looks interesting, but one thing really embarrasses me - you must have a loaded view to configure your view model. Ignores the values from an observable sequence which are followed by another value before due time with the specified source, dueTime and scheduler. Returns the only element of an observable sequence, or a default value if the observable sequence is empty. Returns the elements in an observable sequence with the minimum key value according to the specified comparer. (Defined by, Overloaded. (Defined by, Overloaded. Applies an accumulator function over an observable sequence and returns each intermediate result with the specified source, seed and accumulator. (Defined by, Overloaded. There are two ways to get this last emited value. (Defined by, Converts an observable sequence into a queryable observable sequence. ‘Animals alter their behavior to avoid a variety of different types of predators.’ ‘Data on ancient color could tell us about the environment and behavior of animals.’ (Defined by, Overloaded. behavior definition: 1. the way that someone behaves: 2. the way that a person, an animal, a substance, etc. BehaviorSubject vs Variable vs other subjects.

There are two ways to get this last emited value. (Defined by, Converts an observable sequence into a queryable observable sequence. ‘Animals alter their behavior to avoid a variety of different types of predators.’ ‘Data on ancient color could tell us about the environment and behavior of animals.’ (Defined by, Overloaded. behavior definition: 1. the way that someone behaves: 2. the way that a person, an animal, a substance, etc. BehaviorSubject vs Variable vs other subjects. Notifies all subscribed observers with the exception. Having all properties in classes, controllers, view models as Subjects and/or Units? Merges two observable sequences into a single observable sequence. We've tried to explain and provide examples how one could best use other concepts in RxExample app. One of the variants of the Subject is the BehaviorSubject.
