如何在反应中循环

如何循环重复

这是我的代码

这是App.js

import React from 'react';
import './App.css';
import Child from './Child/Child';

function App() {
  return (
    <div className="container">
      <div className='row'>
        <Child></Child>
      </div>
    </div>
  );
}

export default App;

这是 Child.js

import React from 'react';
import './Child.css';

function Child() {
    return(
        <div className='container'>
            <div className='row'>
                <h1>Mark</h1>
            </div>
        </div>
    )
}

export default Child

如果我的疑问不清楚，请发表评论。

您可以将十个子组件放入一个数组中并渲染它。

const children = []
for(let i = 0; i < 10; i++){
  children.push(<Child key={i}/>)
}
  return (
    <div className="container">
      <div className='row'>
        {children}
      </div>
    </div>
  );
