hello firends,  
this is my function:

```auto
var LastCommands = msg.payload.split('\n')
global.set("LastCommands", LastCommands);
LastCommands.forEach(function(command) {
   // send each "command" with 250ms delay to MQTT node
});

```

How can I send a msg.payload for each iteration in the loop to an other node (MQTT) ?  
Thx !

or instead - use a split node (that will emit one msg per line (\n) - then a delay node in rate limit mode set to 250mS

thx!  
I made it like this:

```auto
var LastCommands = msg.payload.split('\n')
global.set("LastCommands", LastCommands);
LastCommands.forEach(function(command) {
   node.send({payload:command});
});

```

...plus random delay node
