code: func (c *conn) initialize() {
  	// We need this so that received binary data is in ArrayBufferView format so
  	// that it can easily be read.

docs: // initialize adds all of the event handlers necessary for a conn to function.
  // It should never be called more than once and is already called if Dial was
  // used to create the conn.
