Record utility type in Typescript

Record<Keys, Type> Creates a type with a set of properties Keys of the type Type. This is a much easier way of making a typed object.

interface PageInfo {
  title: string;
}

type Page = "home" | "about" | "contact";

const nav: Record<Page, PageInfo> = {
  about: { title: "about" },
  contact: { title: "contact" },
  home: { title: "home" },
};

This requires all values of the Keys to be present in the Record
