A mandatory parameter of 2 optional ones, how can this be described?

Question

typescript

There is a type

export type PropsType = {
    param1?: string;
    param2?: string;
};

This is the component type. Either param1 or param2 dynamically comes to the component. Based on the type described above, nothing may come to the component at all, but either param1 or param2 constantly comes to me. Based on this requirement, how can such a type be described?

Answer 1

type param1 = {
    param1: string
};
type param2 = {
    param2: string
};

export type PropsType = param1 | param2;

So?
