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

使用场景在复杂的，频繁的异步请求场景，使用rxjs。在依赖的多个异步数据，决定渲染的情景，使用rxjs。总之：在前台频繁的、大量的、和后台数据交互的复杂项目里面，使用rxjs（web端，iOS，android端等，客户端都可考虑使用）rxjs初步认识数据和数据观察者的绑定。数据变化，观察者动作——监听或者观察者模式。观察者的迭代执行动作——观察者注册任意个异步或同步动作，迭代执行。hello wo
