Redux是基于纯函数的，为了保证它的“纯度”，它的reducer函数必须是严格的 S' =
f(S) 的形态，所以，与其说Redux是“状态管理”库，不如说它是“状态转移管理”库
，因为Redux是无状态的，状态是在你的程序里的，你自己维持状态，它只是给你提供
了一个状态转移的统一方式。这使得它的整个模型看起来是非常干净。
而事实上我们在开发实际项目当中可能有小半（maybe大半）的reducer场景其实应该是
S' = await fAsync(S) 的形态，比方说，我点了一个计数器+1的按钮，在一个美丽的
DEMO里，它就+1了，但放到生产需求里，很可能是要先发起一个Ajax请求，请求OK了再
+1，甚至这时候不是+1，而是直接和服务端同步一个新的值。
但异步的reducer就破坏了它的“纯度”，因为异步是不确定的，先发不一定先至，这
会破坏reducer的“... 阅读全帖 |

今年，Dan加入facebook，redux就成了legacy。
redux引入一堆概念，一堆依赖，去实现react本身就有的功能。
只能说明搞前端的精力实在太旺盛了。 |

发帖数: 9999 | 3 有些基本的数据，比如用户状态信息，不用redux的话，也得放在root component
state里，因为你不知道什么地方会用到或更新这些信息，这样的话跟global state也
没啥区别，child component想读取或则更新的话，要么通过child context，要么得一

发帖数: 2265 | 4 React+Redux非常精炼，良好运用将发挥出极强劲的生产力。但最大的挑战来自于函数
式编程（FP）范式。在工程化过程中，架构（顶层）设计将是一个巨大的挑战。要不然
做出来的东西可能是一团乱麻。说到底，传统框架与react+redux就是OO与FP编程范式
的对决。

fb更加紧跟形势。狗家还是很传统，guava, angular,其实都是搞java oop的套路。f家

redux什么东西都在一个global的array里。
每次动一下，都要这个array做copy on write。复杂度把做后端的会气死。
还会误用。redux怎么办了？
就是写多大写加下划线的constant，对应很多接受这些constant的action。
所以写的很累，你要记住这些玩意。 |

The story of Texas is a story of migration. In telling this story, a few key
factors emerge.
First, whether you trace your ancestors back to the Lipan Apache, Spanish
explorers or Stephen F. Austin's Old Three Hundred, when you search back far
enough you find that we are all the descendants of people from somewhere

除了引入一堆乱七八糟的小部件，reducer，constant外，有什么优点吗？
后端的基本原则是避免global的东西。
child component可以通过函数改变parent component的state。

不应该追求纯，而是能纯函数的地方尽量纯函数，把side effect限制在一定范围内。

redux可能受elm启发，这方面elm也许做的更好一点，不过我不了解细节。 |

发帖数: 3989 | 36 我工作中也在用 react+redux+TypeScript +mocha+karma+webpack，
初期很难，上手后就好多了。
其实redux很简单，就前期搭框架时是要花点功夫。 后面基本就不会大动了。
另外要习惯ajax call都在 middleware 做然后传actionItem给reducer。。
注意在middleware ajax后改的state都会被丢弃。
用typeScript +tdd的确节约了我不少debug时间。。
我初学时在做了个demo，在github上，有空整理下给大家参考。 |

（以上为起诉的前高盛女员工Shana Orlich（左）与H. Cristina Chen-Oster（右）摄
于纽约市的照片。由《纽约时报》通过Redux网站获得。）
两名前高盛女员工近日称，找到起诉高盛性别歧视的新证据，计划发起集体诉讼。据她
们的上诉文件所说，高盛的工作环境广泛存在性别歧视，充斥“男生俱乐部”（boy’s
club）的氛围。如时不时会有豪饮，甚至去脱衣舞俱乐部寻欢作乐。
两位女士H. Cristina Chen-Oster与Shanna Orlich早在2010年就提起诉讼，当时她们
要求高盛纠正歧视倾向，未明确具体赔偿。这次两人希望扩大原告主体范围，请求曼哈
顿联邦女法官Analisa Torres允许她们代表现任和前高盛助理与副总起诉，案件将涉及
十多年来对高盛的性别歧视指控。
在递交法院的文件中，两人诉称，指控得到了前高盛员工声明、专家统计数据分析、高
盛自己的盈利与升职记录支持。文件写道：
