render props是什么？

render props 是指一种在React组件之间使用一个值作为函数的prop共享代码的简单技术

import React, { Component } from "react";

export default class RenderP extends Component {
  myRender = ({ name }) => {
    return <div>my name is {name}</div>;
  };
  myRender2 = ({ name }) => {
    return <div>my name is {name}</div>;
  };
  render() {
    return (
      <div>
        <DataProvider render={this.myRender} />

        <DataProvider render={this.myRender2} />
      </div>
    );
  }
}

class DataProvider extends Component {
  state = {
    name: "Tom",
  };
  render() {
    return (
      <div>
        <button onClick={() => this.setState({ name: "luyi" })}>luyi</button>
        <p>共享数据组件自己内部的渲染逻辑</p>
        {this.props.render(this.state)}
      </div>
    );
  }
}
