解析: React中有两种组件:函数组件(Functional Components)和类组件(Class Components)。据我观察,大部分同学都习惯于用类组件,而很少会主动写函数组件,包括我自己也是这样。但实际上,在使用场景和功能实现上,这两类组件是有很大区别的。 来看一个函数组件的例子: 代码语言:javascript 复制 functionWelcome=(props)=>...
在React里面有两种组件, Class components(类组件) 和 Functional components(函数式组件).两者有明显的区别,比如 Class Components 是属于ES6的类 Functional Components 是一个函数,它返回一个JSX组件 什么是Functional Components 先看一段代码: function Hello(props){ return Hello {props.name} } 这是一个函数式...
Sure, they come with different ways of doing things, but if you want to know if a component is a functional or class-based, you just need to look at whether it’s defined as a function or as a class. TIP: One important requirement for writing both function components and class componen...
