JS] console.log JSON Depth 표기 하는 방법.

보통 로그를 작성할 때 JSON.stringify를 사용하면 아래와 같이 사용한다.

// 콘솔 로그 작성
console.log('==> log : ', JSON.stringify(events));

출력 결과물은 아래와 같이 정신없이 나온다...

위 처럼 나오는 JSON을 댑스가 있도록 표기하는 방법을 알아보자.

 

// JSON 표기 로그 작성
console.log(`==> JSON : , ${JSON.stringify(events, null, 4)}`);

 

출력결과물

짠? 아래와 같이 예쁘게 알아볼 수 있게 나오는 것을 확인할 수 있다!!
