I've found myself what I needed to solve the situation.

Had a similar requirement the other day, did it like this:

```javascript
//function (index, item) {

function swapElements(array, index1, index2){
var temp = array[index1];
array[index1] = array[index2];
array[index2] = temp;
};

const name_arr = item.name.split('_');
swapElements(name_arr, 0, 1);

return name_arr.join("_");
//}
```
