New Idea, New the World.
技术也是时尚驱动的，我们常常臣服于时尚，面对快速的变化常常让我们局促不安， 开始焦虑，唯恐错过了些什么。怎么打破这种焦虑？需要在快速变化得世界里保持清醒， 保持独立的思考和认知。 让我们回归到技术的本质, 因为解决了真实的问题，技术才变得有价值。 真正牛*的技术，都是静悄悄的跑在线上...
Reactive and Predictable state container for React or ReactNative.
- Thanks Immutable.js
- Thanks MapReduce
- Thanks Functional Reactive Programming.
很早很早之前，我们爱上了React and immutable，所以就有了很简单的iflux。
iflux = immutable.js + react.js
保持简单

| React App |-----|
+------------------------+
| <Layout> |
| <SearchForm/> |
| <Toolbar/> |
| <DataGrid/> |
| </Layout> |
+------------------------+
优点：
- 简单直接，几乎没有什么规则
- 单根数据源(single data source)
- Immutable fronted UI
- High Performance
但是随着业务的不断的发展，数据层的复杂度也在上升。这时候iflux就会暴露出很多的缺点
- Big Store, Store中大量的数据和业务的处理，代码膨胀的厉害
- Store是单例，不销毁，有共享的问题
- store的数据通过props不断的透传，代码写的很费劲
- 大量的数据之间的依赖关系，需要手动的保证和处理
- 使用MapReduce的理念解决big Store
- 使用@Relax自动注入store中的数据和事件
- Store不再是单例
- 使用FRP的理念, 简单的实现反应式数据，抽象源数据和派生数据
这就是我们的iflux2
