OR interfaces?

What should EITHER mean?

interface ONE {
  one: number;
  i: string;
}
interface TWO {
  two: number;
  j: string;
}

type EITHER = ONE | TWO;

interface ONE {
  one: number;
  i: string;
}
interface TWO {
  two: number;
  j: string;
}

type EITHER = ONE | TWO;

EITHER seems to accept anything that has * ALL the elements of either ONE or TWO, along with * zero or more elements of the other.

A union type like this means that it the type is actually atleast One or Two which means that sometimes a combination of both is also allowed If you want them to be exclusive then adding the same property with a different type can help Like kind: "One" and kind: "Two"

how would I say that I want it to be exactly one of the them (ie: to have exactly 2 elements in it)
