Is there a race in the websocket API. When you do: var ws = new WebSocket("ws://mysite.com","myprotocol"); then the spec says: Return a new WebSocket object, and continue these steps in the background (without blocking scripts). Establish a Web Socket connection to a host host, on port port (if one was specified), from origin, with the flag secure, with resource name as the resource name, and with protocol as the protocol (if it is present). So if the next line in the script is ws.onopen=myopenfunc; there is a race between if the onopen function will be assigned and if the background connection has been established? OK it is currently unlikely that the connect will happen that quick - however if I'm running in a rhino test environment or a on a browser that is multiplexing the websocket onto an already existing connection, then the onopen may indeed be fast. Similar races exist for onmessage and onclose. Setting onmessage might miss a message that is delivered quickly after the websocket is opened. regards
