rxJs并不是专门给angular用的，其实是专门给javascript用的。但是angular深度的集成了rxjs 由于课程有限，并不会对rxjs做深入的剖析，有兴趣的可以看高级课程会花相当大时间去讲解rxjs 支持很多的语言。 把脏值检测这个模板child删掉先。 child组件直接删掉 一个输

一 concat，merge，zip，combineLatest等合并类操作符
以上操作符在版本6中已经只存在静态方法，不能在pipe中使用。
import {concat,merge,zip,combineLatest}
1.concat (obs1,obs2,obs3) 首尾相连
依次将多个observable首尾合并，必须在第一个obs1的数据全部完成，才能进行第二个obs2，如果第

最近在研究RxJS的编程思想，与OOP不同，RxJS更像是事件驱动+观察者模式，前一篇文章有所介绍。有经验的读者想必会有个疑问：Observable与Promise模式，或者说OOP到底区别在哪里，能带来什么不同呢？ 我的理解是(此处为个人理解)：Observable更好地实现了解耦。如同我们用消息 ...

什么是 RxJSRxJS是一个用于响应式流的库，它基于Observables（可观察对象）和Operators（操作符）的概念。它提供了一种响应式编程的方式，使得异步数据流和事件更容易管理和组合。 什么是流流可以被视为一个持续的事件序列。它可以是由用户交互、网络请求、定时器等事件触发的数据序列。这?些事件产生的数据会被发送到流中，然后可以被观察者（Observer:是一个回调
