1.syntax 语法:functional component语法更简单,只需要传入一个props参数,返回一个react片段。class component 要求先继承React.Component然后常见一个render方法,在render里面返回react片段。下面是两者被Babel编译过的代码 2.state 状态:因为function component 知识一个普通的

React’s components follow many of the best principles of functional programming, except they’re objects. For instance, given a single set of parameters, a React component will always render the same output—no matter how many times it’s rendered, no matter who renders it, no matter where...
Alternatively, press CtrlAltShift0T and select Convert to Functional Component from the popup. Destructuring in a React application Destructuring lets you easily unpack values from arrays and objects into variables. This functionality has a very concise syntax that is often used when you need to...
