简单的徽章展示，当 count 为 0 时，默认不显示，但是可以使用 showZero 修改为显示。

en-US

Simplest Usage. Badge will be hidden when count is 0, but we can use showZero to show it.

import { Badge, Icon } from 'antd';

ReactDOM.render(
  <div>
    <Badge count={5}>
      <a href="#" className="head-example" />
    </Badge>
    <Badge count={0} showZero>
      <a href="#" className="head-example" />
    </Badge>
    <Badge count={<Icon type="clock-circle" style={{ color: '#f5222d' }} />}>
      <a href="#" className="head-example" />
    </Badge>
  </div>,
  mountNode
);
