We can use the utility type Record to construct an object type using certain key/value pairs in order to link to the properties of an object which contains different data types.


interface Person {
    age: number;
    gender: string;

type PersonName = "adam" | "bilal" | "aisha";

const people: Record<PersonName, Person> = {
    adam: {age: 20, gender: "Male"},
    bilal: {age: 25, gender: "Male"},
    aisha: {age: 23, gender: "Female"}

console.log(people.aisha) // {age: 23, gender: "Female"}
