RxJS的基本概念
什么是RxJS?Reactive Extension JavaScript. It's a reactive streams library that allows you to work with asynchronous data streams. 什么是asynchronous data streams?1. asynchronous: When we called a function and want to be notified when the result is available,we will have to register a callback. In this way,we can continue with execution without worrying about the webpage becoming unresponsive. 2. data: Raw information in JavaScript. 3. streams: Sequences of data,in other words,information made available over time. Different from arrays,it doesn't have to be present in order. 何谓observable sequences?就是observables。Observables are flexible and have to patterns: push and pull. push pattern: We use the push pattern to subscribe to the source stream and react to new data. pull pattern: We use the pull pattern in the same way above but,synchronously.
