Rabbitmq not connecting from Paho js client

Question

Here is my paho javascript client code

  client = new Paho.MQTT.Client(host, Number(port), clientId);

  client.onMessageArrived = onMessageArrived;
  client.onMessageDelivered = onMessageDelivered;
  client.onConnectionLost = onConnectionLost;

here port 8083 works with other broker but not with Rabbitmq. In the documentation I could not found any correct port number.

Running sudo rabbitmqctl status gives

  [{rabbitmq_management,"RabbitMQ Management Console","3.6.2"},
      {rabbitmq_web_dispatch,"RabbitMQ Web Dispatcher","3.6.2"},
      {webmachine,"webmachine","1.10.3"},
      {mochiweb,"MochiMedia Web Server","2.13.1"},
      {rabbitmq_mqtt,"RabbitMQ MQTT Adapter","3.6.2"},
 {listeners,[{clustering,25672,"::"},{amqp,5672,"::"},{mqtt,1883,"::"}]},

So I tried with port 1883 also. I was following https://github.com/rabbitmq/rabbitmq-web-mqtt-examples/blob/master/priv/echo.html

I getting this error:

WebSocket connection to 'ws://localhost:1883/mqtt' failed: Connection closed before receiving a handshake response

Have you installed the mqtt-web plugin (https://github.com/rabbitmq/rabbitmq-web-mqtt)? MQTT over websockets is not going to be on the same port as pure MQTT — hardillb, May 26 '16 at 06:55
no i havnt installed this but as I i have mentioned `{rabbitmq_mqtt,"RabbitMQ MQTT Adapter","3.6.2"}` is shown by rabbitmq — Manish Kumar, May 26 '16 at 10:19

As thrashed out in the comments:

Rabbitmq requires the following plugin to support MQTT over websockets (http://github.com/rabbitmq/rabbitmq-web-mqtt)
