Hi, I try to explain .....  
this is the code:

![img1](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/f/8/f850651a94523a11f473c3cd9e2a94ff08c8ddf7.png)

```auto
const output = [null, null];

const x = msg.payload

if (x == 1)
{
    output[0] = { payload: "uno" }
    output[1] = { payload: "due" }
    setTimeout(() => { node.send(output[0]) }, 6000)
    setTimeout(() => { node.send(output[1]) }, 0)
}

```

I have the correct delay but for the same node (0) instead of "uno" for output [0]  
and "due" for output [1]

Where am I wrong?

That output looks correct to me. You are sending `output[1]` after a zero ms timeout so it appears first and `output[0]` after a 6s delay. What did you expect?

Of course, a timeout with a zero delay is a bit pointless I think.

The second image ....  
both node: 0  
Instead

```auto
output[1] = { payload: "due" }

```

should be node: 1

Urm, afraid not. Because you've only passed 1 element of `output` to each node.send. So both messages will appear from the top port of the function node and go to the debug marked `0` on your flow.

I think what you meant to do was something like this:

```auto
const output = [null, null];

const x = msg.payload

if (x == 1)
{
    output[0] = { payload: "uno" }
    output[1] = { payload: "due" }
    setTimeout(() => { node.send( [output[0], null] ) }, 6000)
    setTimeout(() => { node.send( [null, output[1]] ) }, 0)
}

```

If, instead, you did

```auto
const output = [null, null];

const x = msg.payload

if (x == 1)
{
    output[0] = { payload: "uno" }
    output[1] = { payload: "due" }
    setTimeout(() => { node.send(output) }, 6000)
    setTimeout(() => { node.send(output) }, 0)
}

```

You would get 4 outputs.

</div>

Try

```auto
const output = [[null,null], [null,null]];

const x = msg.payload

if (x == 1)
{
    output[0][0] = { payload: "uno" }
    output[1][1] = { payload: "due" }
    setTimeout(() => { node.send(output[0]) }, 6000)
    setTimeout(() => { node.send(output[1]) }, 0)
}

```

OR

```auto
const output = [[null],[null]]
const x = msg.payload

if (x == 1)
{
    output[0].unshift({ payload: "uno" })
    output[1].push({ payload: "due" })
    setTimeout(() => { node.send(output[0]) }, 6000)
    setTimeout(() => { node.send(output[1]) }, 0)
}

```

Yes .....

```auto
const output = [null, null];

const x = msg.payload

if (x == 1)
{
    output[0] = { payload: "uno" }
    output[1] = { payload: "due" }
    setTimeout(() => { node.send( [output[0], null] ) }, 6000)
    setTimeout(() => { node.send( [null, output[1]] ) }, 0)
}

```

This is correct for me.  
Thank you very much .....
