Obtaining exclusive properties in TypeScript: Extracting Class-Specific Properties

class A {
    baseField: number;
}

class B extends A {
    nonInherited: number;
}

type onlyNonInherited = SelectOnlyNonInherited<B>;

I am looking to define my onlyNonInherited type as:

interface NonInherited {
    nonInherited: number;
}

Can someone assist with the definition of SelectOnlyNonInherited? I have searched through multiple resources without success :(

Answer №1

By solely examining the type B, achieving this task is unattainable. Nevertheless, you can implement a solution such as:

type ExcludingInherited = Omit<B, keyof A>;
