I have to arrays which are related.

```
shortArray = ["ID-111", "ID-222"]
longArray = ["ID-111 bis", "ID-222 bis"]

```

I created them like that because I needed unique IDs in previous steps and now I must use the same color for each pair in the chart I'm drawing them.

My aim is to generate a string with this form:

```
{
    "ID-111 bis" : chart.color("ID-111"),
    "ID-222 bis" : chart.color("ID-222"),
    ...
}

```

I tried to do it like this:

```
 const result = {}
 for(const item of longArray) {
    result[item]=[];
    result[item].push({item : "chart.color(" + shortArray+ ")"});
 }

```

Which gives me this wrong output:

```
{
"ID-111 bis" :[{item: "chart.color(ID-111,ID-222)"}],
"ID-222 bis" :[{item: "chart.color(ID-111,ID-222)"}]
}

```

Any ideas what should I change?

**LATER EDIT:**

I saw many answers which are pretty similar but there is a condition that must be respected:

The second argument should **not** be in quotes.

`"ID-111 bis" : chart.color("ID-111")` - good

`"ID-111 bis" : "chart.color("ID-111")"` - bad
