给这个纯函数输入一些应用程序的状态,就会得到相应的 UI 描述的输出,这个过程不会去直接操作实际的 UI 元素,也不会产生所谓的副作用。 React 组件树的测试 按理来说按照纯函数这样的思路,React 组件的测试应该很简单的说。但与此同时,对 UI 渲染的组件树进行测试依然存在一个问题,从下图中可以看出,越处于上层的...
React’s aim is to solve the various challenges of building user interfaces that rely on changing data. Although React is a simple JavaScript library and is easy to get started with, it is still possible to misuse it in ways that deny the web app from reaping the benefits that React has...

React Context & useReducer Mobx Recoil react-sweet-state hox 这几个都是我接触过的,Npm 上的现状和趋势对比: 毫无疑问,React和Redux的组合是目前的主流。 今天5月份, 一个名叫Recoil.js的新成员进入了我的视野,带来了一些有趣的模型和概念,今天我们就把它和 Redux 做一个简单的对比, 希望能对大家有所启发...

React官方网站是这样形容React的,A JavaScript library for building user interfaces。React实际上是一个编写页面的UI框架,或者说他只是一个UI的library,一个库而已。 虽然React只是一个UI的library,不过他渲染页面的方式却是值得我们学习的。通过JSX动态的生成DOM来渲染页面UI。他没有架构,没有模板,没有设计模式,没...
