[React] Return a list of elements from a functional component in React

We sometimes just want to return a couple of elements next to one another from a React functional component, without adding a wrapper component which only purpose would be to wrap elements that we want to render.

In this one minute lesson we are going to learn how to solve this problem by returning an array of components and as such - avoid adding unnecessary div wrappers.

Way 1:

import React from "react";
import "./App.css";

const App = () => {
  return (
    <>
      <div className="box">One</div>,
      <div className="box">Two</div>,
      <div className="box">Three</div>
    </>
  );
};

export default App;

Way 2:

import React from "react";
import "./App.css";

const App = () => {
  return [
    <div className="box">One</div>,
    <div className="box">Two</div>,
    <div className="box">Three</div>
  ];
};

export default App;

React.Component 与 React.PureComponent(React之性能优化)

前言 先说说 shouldComponentUpdate 提起React.PureComponent,我们还要从一个生命周期函数 shouldComponentUpdate 说起,从函数名字我们就能看出来,这个函数是用来控制组件是否应该被更新的. React.PureComponent 通过prop和state的浅对比来实现shouldComponentUpate(). 简单来说,这个生命周期函数返回一个布尔值. 如果返回true,那么当props或state改变的时候进行更新: 如果返回fal
