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.
