Therefore, a large number of application development are quietly developing using this popular pattern. It supports use cases with no value, one value or n values (including infinite sequences). Both the error signal and the completion signal terminate the sequence. Publishers can push new elements to subscribers by calling the next () method, send an error signal by calling the onerror () method, or send a completion signal by calling oncomplete (). In addition to push elements, responsive programming also defines good error handling and completion notification. In addition, the operation applied to the push element is declarative rather than imperative: what the programmer needs to do is to express the logic of calculation rather than describe the precise control process. When a new available element appears, the publisher notifies the subscriber that this “push” is the key to the response. In the responsive flow, publisher subscriber corresponds to the iteratable iterator. Using iterators is imperative programming in which the developer decides when to access the next () element in the sequence. One of the main differences is that the iterator is based on “pull” and the responsive flow is based on “push”. You can also compare the responsive flow pattern with the iterator pattern. In object-oriented programming languages, responsive programming is usually presented as an extension of observer mode.

It is designed to simplify the MVC software architecture. The original purpose of responsive programming is to simplify the creation of interactive user interface and the rendering of real-time system animation. The use of responsive programming paradigm means that static or dynamic data streams can be expressed more conveniently in the programming language, and the relevant calculation model will automatically propagate the changed values through the data stream. “Intra-National Versus International Trade: How Stubborn are Nations in Global Integration?,” National Bureau for Economic Research Working Paper 5531, 1996.The so-called responsive programming refers to a programming paradigm oriented to data flow and change propagation.
