on method

void on(
  1. String eventType,
  2. Function handler
)

A "change" event is fired on startup right after TalkJS loads, as well as every time the amount of unread conversations changed. The handler is invoked with an array of objects with limited information about each conversation, see {@link UnreadConversation}.
