it was called with one argument, the result is that argument. If it was

This script pops up an alert box that says "You said: Hello, world".
Web browsers allow any site to open a websocket connection to any other,
instead of using the same-origin policy that governs other network
access from javascript. This can be surprising and is a potential
security hole, so since Tornado 4.0 `WebSocketHandler` requires
applications that wish to receive cross-origin websockets to opt in
by overriding the `~WebSocketHandler.check_origin` method (see that
method's docs for details). Failure to do so is the most likely
cause of 403 errors when making a websocket connection.
When using a secure websocket connection (``wss://``) with a self-signed
certificate, the connection from a browser may fail because it wants
to show the "accept this certificate" dialog but has nowhere to show it.
You must first visit a regular HTML page using the same certificate
to accept it before the websocket connection will succeed.
