You may notice that up to now you have only been increasing the user count. Handling a user disconnecting is just as easy as handling the initial connect, except you have to listen for it on each socket instead of on the whole server.
你也许注意到，目前为止我们只处理用户数量的增加，没有处理减少。 事实上，处理用户断开连接也很简单。 区别在于，新连接的监听是发生在整个服务器上，但连接断开的监听是发生在每个 socket 上。
To do this, add another listener inside the existing `'connect'` listener that listens for `'disconnect'` on the socket with no data passed through. You can test this functionality by just logging that a user has disconnected to the console.
为此，我们需要在目前的 `'connect'` 监听里面添加另一个监听器，监听 socket 断开连接 `'disconnect'` 的事件。 通过登录已与控制台断开连接的用户，你可以测试这个功能。
```js
socket.on('disconnect', () => {

To make sure clients continuously have the updated count of current users, you should decrease the currentUsers by 1 when the disconnect happens then emit the 'user count' event with the updated count!
为确保客户端可以看到实时的用户数量，我们应该在用户断开时让 currentUsers 减 1，然后发送 “user count” 事件，并使用修改后的用户数量。
**Note:** Just like `'disconnect'`, all other events that a socket can emit to the server should be handled within the connecting listener where we have 'socket' defined.
**注意：**和 `'disconnect'` 类似，所有 socket 可以发送到服务器的事件，我们都应该在有 “socket” 定义的连接监听器里处理。
