react-handbook's Issues

Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null

Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null

遇到这错误是 React render Component 的时候,return 了 undefined 值的情况。你要注意 return 后返回的是返回不正确组件。

比如下面这个情况很多时候就会出现上面的错误:

Wrong

render() {
    return
    (
        <div>Here comes JSX!</div>
    )
}

Correct

  render() {
        return (
             <div>Here comes JSX!</div>
        )
  }
