react中props属性类型校验定义(未使用ts)

import React from 'react'
import { useState } from 'react'
import PropType from 'prop-types'
// 生成Demo 类组件
class Demo extends React.Component {
  render() {
    return (
      <div>
        <h1>{this.props.money + 100}</h1>
        <h2>{this.props.name.toUpperCase()}</h2>
      </div>
    )
  }
}
Demo.propTypes = {
  money: PropType.number,
  name: PropType.string,
}
function App() {
  const [state, setState] = useState('')
  const handleClick = (value) => {
    setState(value)
  }
  return (
    <div className="App">
      <Demo money={100} name="zhangsan"></Demo>
    </div>
  )
}

export default App
