Optional Values of Type

5 years ago

👍

Anyone know if its possible to get the Optional values of a type?

interface A {
  a: string;
  b?: string;
  c?:string;
  d: string;
}

type B = OptionalsOf<A>;

so B becomes something like

type B = {
  b?: string;
  c?: striing;
};

Though for my usecase I will do something like

type B = Required<OptionsOf<A>>;

But I presume that wouldn't make a difference?
