Container 组件

const Container = ({ classes, children }) => (
  <Paper elevation={4} className={classes.root}>
    {children}
  </Paper>
)

错误JSX 代码

{
    (createdTopics && createdTopics.length > 0) && (<List><TopciListItem /></List>)

  (createdTopics && createdTopics.length > 0) 
  ? (<List><TopciListItem /></List>)
  : null
}
