How to type a map function that receives different types of arrays?

Question

I have created the following function and I need to type the i argument that is currently an any:

1. scenario - with value and label

2. scenario - with id and name

3. scenario - without extra properties

And my main problem is that I can receive an array that has different property names, like:

const status: {
    status: number;
    label: string;
}[],
const departments: {
    id: number;
    name: string;
}[]

so my i sometimes can be status and label but can also be id and name. So how to properly type this i? I tried using unknown but I get this message:

Answer 1

Try set i to both types instead of any:

const handleMap = (arr: Array<unknown>, filterValue?: string, filterLabel?: string) => {
    return arr
        ? arr.map((i: status | departments) => ({
                value: i.toString(),
                label: i,
          }))
        : [];
};
