Record type allows you to create object types in a shorter way. Types for objects are normally defined in the below format:

type UserDetailType = {
  name: string;
  age: string;
};

type Users = {
   [name: string]: UserDetailType
};

However, with the Record utility you can construct the same type as follows

type UserDetailType = {
  name: string;
  age: string;
};

type Users = Record<string, UserDetailType>;
