Можно ли задать гибридный тип данных в ts?

export interface IRoomData {
    adults: number;
    children: number;
    childrenAges: number[]|{age: any}[];
}

if(this.roomsData){
          this.roomsData = this.roomsData.map((room) =>{
            for(let i = 0; i < room.childrenAges.length; i++){
              room.childrenAges[i] = {age: room.childrenAges[i]};
            }

            return room;            
          });
        }
