标记为continue语句；for循环

Question

continue connloop;抛出Syntax Error: Unsyntactic continue。

如果我将continue connloop;更改为continue;，它将运行(但它当然不会在外部循环上执行，而是在内部循环上执行)

为什么会发生这种情况，这在nodejs/ecma6中是不推荐的还是非法的？

请不要建议我使用函数调用而不是标签。

redisSubscriber.on("message", function(channel, event){

event = JSON.parse(event);
const eventPayload = JSON.stringify(event.payload);

 connloop:
  for(let conn in connections){
  conn = connections[conn];
  redisClient.SMEMBERS('connection/'+conn.id+'/subscriptions', (err, subscriptions)=>{

      let intersectedTags = [];
      if(event.address.tags.length > 0 && subscriptions.length > 0){         
        for(let tag in subscriptions){
          tag = subscriptions[tag];

          for(let _tag in event.address.tags){
            _tag = event.address.tags[_tag];
            if(tag == _tag)
              intersectedTags.push(tag);

          }
        }
      }

      let exclusive = false;
      for(let userId in event.address.include){
        userId = event.address.include[userId];
        if(userId == conn.userId){
          exclusive = true;
          break;
        }
      }

      if(intersectedTags.length > 0 || exclusive){
        if(event.address.exclude){
          for(let exclude in event.address.exclude){
            exclude = event.address.exclude[exclude];
            if(exclude == conn.userId){
              continue connloop;
            }
          }
        }
        const browserEvent = {tags: intersectedTags, notification: eventPayload, exclusive};
        conn.write(JSON.stringify(browserEvent));
      }
  })
} });
