The code checks if the incoming payload is an array. If so, each element of the array is split into a separate message and forwarded to the appropriate outputs. If there are more array elements than outputs, the additional messages are all sent to the last output. If the incoming payload is not an array, the message is passed through unchanged.(...) If there are more elements than outputs, send the remaining elements to the last output
node.send([null, newMsg]);
