TypeScript: deep partial?

Is there a way to specify a partial type in TypeScript that also makes all child objects partials as well? For example: interface Foobar { foo: number; bar: { baz: boolean; qux: string; }; } const foobar: Partial<Foobar> = { foo: 1, bar: { baz: true } }; This throws the following error: TS2741: Property 'qux' is missing in type '{ baz: true; }' but required in type '{ baz: boolean; qux: string; }'
