 ## Comparison with Fire Event API
 
 Fire Event is our original event simulation API. It can invoke **any event handler** declared on **either host or composite elements**. Suppose the element does not have `onEventName` event handler for the passed `eventName` event, or the element is disabled. In that case, Fire Event will traverse up the component tree, looking for an event handler on both host and composite elements along the way. By default, it will **not pass any event data**, but the user might provide it in the last argument.
