How to combine flowjs type definitions

Question

How can I combine the following type definitions, so I dont have to repeat myself?

type Lama = {|
name: string,
|};

type LamaWithHat = {|
name: string,
hat: string,
|};

Tried using Interseptions but appearently the syntax might be wrong:

type LamaWithHat = {|
hat: string,
|} & Lama;

Answer 1

How about if we do this /* @flow */

type Lama = {|
name: string,
|};

type LamaWithHat = {|
...Lama,
hat: string,
|};

const a: Lama = {
    name: 'rahul'
}

const b: LamaWithHat = {
    name: 'rahul',
    hat: 'circluar'
}
