[TypeScript] Typescript Interfaces vs Aliases Union & Intersection Types

TypeScript has 'interface' and 'type', so when to use which?

interface hasName {
    firstName: string;
    lastName: string;
}

interface hasAddress {
    address: string
}

type Player = (hasName & hasAddress) | null;

let player: Player = {firstName: 'Joe', lastName: 'Jonse', address: 'USA'};

It is recommended that to use 'interface' to define the props that obj should have.

'type' is recommended to use when combine multi interfaces to descide a single object like what we show in example.
