+Here we create a function `broadcastSessionCount` that broadcasts a value with the current total session count exposed to us under the [Channel `sessionCount` property](/better-sse/reference/api/#channelsessioncount-number) with the event name `session-count`.
 
 We then listen on both the events `session-registered` and `session-deregistered` and set the `broadcastSessionCount` function as a callback for each. This way, every time a session joins or leaves the channel the count is re-broadcasted and updated for all of the existing sessions on the channel.
