React实现类似于Vue中的插槽的项目实践

// 创建项目
npx create-react-app my-app --template typescript

// 运行项目
yarn start

// NavBar.tsx

import React from 'react'
import './navbar.css'

type Props = {
  children: any[]
}
const NavBar = (props:Props) => {
  return (
    <div className='navbar-container'>
      <div className='navbar-left'>
        {props.children[0]}
      </div>
      <div className='navbar-center'>
        {props.children[1]}
      </div>
      <div className='navbar-right'>
        {props.children[2]}
      </div>
    </div>
  )
