인프런 커뮤니티 질문&답변

export type Event =
  | {
      type: "click";
      event: MouseEvent;
    }
  | {
      type: "focus";
      event: FocusEvent;
    }
  | {
      type: "keydown";
      event: KeyboardEvent;
    };

type ClickEvent = Extract<Event, {type:'click'}>;

type tests2 = [Expect<Equal<ClickEvent, { type: "click"; event: MouseEvent }>>];

에러 없는거 보니 정답인것 같습니다!
