We need to call the open method by creating a WebSocket object inorder to make a WebSocket connection. How can we do that?

Answer:

First of all, there is no "open" method on the WebSocket object. However, when we want to create a WebSocket object for establishing a connection, we basically instantiate the WebSocket object that does the trick.

e.g.

var uri ='ws://echo.websocket.org/';

var webSocket = new WebSocket(uri);
