emit(eventName, ...args)

Triggers an event, calling all registered listeners with the provided arguments.

Parameters:

• eventName (string) – Event to trigger.
• ...args – Any number of arguments to pass to listeners.

Returns: The EventEmitter instance (supports chaining).

Example:

          
            1emitter.on("update", (oldVal, newVal) => {2  console.log(`Changed from ${oldVal} to ${newVal}`);3});5emitter.emit("update", 1, 2); // Logs: Changed from 1 to 2
          
        

Edge Cases:

• If no listeners exist for the event, emit does nothing.
• Errors in one listener do not prevent other listeners from executing; they are logged to console.
