reactjs – Typescript React,从无状态功能组件渲染数组

You can now return an array of elements from a component’s render method.

这适用于常规类组件的typescript,但我不能让它适用于无状态功能组件.

如果您想自己复制,请参阅this repo.

码：

import * as React from 'react';

// See this example working in a non-TS environment: https://codesandbox.io/s/ppl3wopo8j
class Hello extends React.Component {
    render() {
        return <div>
        <Foo />
        <Bar /> {/* Error: 'JSX element type 'Element[]' is not a constructor function for JSX elements. */}
      </div>;
    }
}

class Foo extends React.Component {
    render() {
        return [<div>foo</div>,<div>fooz</div>];
    }
}

function Bar() {
    // Cannot render an array from a SFC
    return [<div>bar</div>,<div>baz</div>];
}

构建此snipper会导致以下错误：

'JSX element type 'Element[]' is not a constructor function for JSX elements.
  Property 'render' is missing in type 'Element[]'.'

如您所见,从常规类组件渲染数组有效,但在从无状态功能组件渲染数组时失败.

我不确定问题是我的代码/设置,DefinitelyTyped反应类型,还是打字稿本身.
