function ArryElement() {
  return [
    <div key='1'>1</div>,
    <div key='2'>2</div>
  ];
}

function App() {
  return <ArryElement />
}

This is because React is expecting to return an object. What you do in this example, is return an array instead.

这是因为 React 期望返回一个对象。你在这个例子中所做的是返回一个数组。

As a user mentioned above, wrapping it in a Fragment(which is an object) will solve the case

正如上面提到的用户,将它包装在一个Fragment(它是一个对象)中将解决这个问题
