Question

Update the mandatory fields in the required interface to extend to another interface, while ensuring that all subfields become

Currently, I have defined 2 interfaces:

interface BattleSkills {
  strength: number;
  armor: number;
  magic_resistance: number;
  health: number;
  mana: number;
  intelligence: number;
  accuracy: number;
  agility: number;
  critical_damage: number;
}

and

interface Item {
  id: string;
  name: string;
  price: number;
  stats: BattleSkills;
}

Right now, Item['stats'] mandates all fields from BattleSkills. How can I modify this so that the stats field remains required, but each of its subfields become optional? It would be better if the fields within BattleSkills remain mandatory themselves.

Answer №1

If you're working in TypeScript, you have the option to utilize the Partial utility type. This is a useful feature that allows you to make certain properties optional within an interface:

interface Product {
  id: string;
  name: string;
  price: number;
  info: Partial<ProductDetails>;
}

The Partial function creates a new type with all properties from the original type, but sets them as optional.
