passed, let us simply say what is responsive programming. Here also do not talk nonsense, quote a paragraph, see understand nature understand, don't understand still don't understand What is reactive programming: Reactive programming (

Most of the content below is translated.REACTIVE programming?What is reactive programming?To understand the motivations behind the reactive--from the programming paradigm, it is important to understand the challenges that developers and companies have not faced ten years ago

About reactive Extensions (Rx)for reactive Extensions (Rx), let's take a look at the official description from Microsoft: The reactive Extensions (Rx) is a library for composing asynchronous and event-based programs using observable sequences a nd linq-style query operators. Using Rx, developers represent asynchronous data streams with observables, query

understanding.Roland Kuhn at the beginning of the video, introducing what to say this week: In this last week of the reactive programming course, we'll focus first on something which is implicitly there alrea Dy. Namely, that actors as independent agents of computation is by default distributed. Normally you run them just on different CPU ' s in the same system. But, there are nothing stopping the run

This lesson helps your think in reactive programming by explaining why it's a beneficial paradigm for programming. See how reactive programming helps you understand the dynamic behavior of a value evolving over time.It allows specify the dynamic behavior of a value completel

RxJS is super when dealing with the dynamic value.Let's see a example which not using RxJS:var a = 4; var b = A * Ten// + = 5// So to change a, it won ' t affect B's value because B is already defined ....So if you want B get sideeffect, you need to declear it again:var a = 4; var b = A * Ten// = 5 = A *// And also, many a time, it may happened so you found the variable had been mutated, but you had no idea where and how.So using RxJS:var streama = Rx.Observable.interval (+). Take (5); var s

What is functional reactive programmingHttp://limboy.me/ios/2013/06/19/frp-reactivecocoa.htmlFunctional reactive Programming (hereinafter referred to as FRP) is a programming paradigm that responds to change. Let's take a look at a small piece of codea = 2b = 2c = a + b // c is 4b = 3// now what is the value of c?If yo

Stateful Objects A Stateful object One normally describes the world as a set of objects, some of which hasState This changes over the course of time.An object with a state if it behavior is influenced by it history.An object is stateful if its behavior is influenced by historyEXAMPLE:A bank account had a state, because the answer to the question"Can I withdraw CHF?"May vary over the course of the lifetime of theAn account is stateful because of the question: Can I take 100 dollars? May not

1.Data structures with maps and FlatMap seem to be quite common.In fact there's a name describes this class of a data structuresTogether with some algebraic laws that they should has.They is called monads.Data structures with map and flatmap are very commonClasses with such data structures plus some algebraic rules are called monads.2. Flatmap and UnitA monad M is a parametric type m[t] with the operations, FLATMAP andUnit, that has to satisfy some laws.Trait M[t] {def flatmap[u] (f:t = M[u]): M
