这是一个react-redux做的 todolist 小demo
createStore 可以帮助我们创建一个store
store.dispatch 帮助我们派发action 这个action会传递给store
store.getState 获取到store里面所有的数据内容
store.subscribe 可以让我们订阅(监听) store的改变 只要store发生改变， 这个方法的回调函数就会执行。
redux-thunk中间件 可以使action返回的不单单只是一个对象，还可以是一个函数

尽量将UI组件与容器组件分离开来。 UI组件内部只有一个render函数负责渲染页面。 容器组件负责其它函数及数据的逻辑操作。容器组件(父组件)与UI组件(子组件）通过props传递数据。
-
如果UI组件只有render函数 可以把它定义为无状态组件。无状态函数创建的是无状态组件，它只是一种只负责展示的纯组件。
使用无状态组件的好处
- 无状态组件的简洁性
- 没有 this「由于使用的是箭头函数事件无需绑定」
- 便于测试
- 没有生命周期钩子，速度快。
<<<<<<< HEAD This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
You can learn more in the Create React App documentation.
