4.children属性

children属性和vue的slot相似

//父组件
import Son from './son'

export default class index extends Component {
  render() {
    return (
      <div>
        index
        <Son>
          <p>children属性</p>
        </Son>
      </div>
    )
  }
}

//子组件
import React, { Component } from 'react'
export default class index extends Component {
  render() {
    return (
      <div>
        index
        {this.props.children}
      </div>
    )
  }
}
