JSON 직렬화 | 기능별 학습

JSON 개체를 직렬화하는 경우 아래 코드에 나열된 옵션과 같은 몇 가지 옵션을 설정할 수 있습니다: 그런 다음 JSON.stringify 함수를 사용하여 JSON 개체를 직렬화할 수 있습니다. JSON 개체는 Spread의 toJSON에서 다음 옵션과 함께 가져옵니다: JSON 문자열을 비직렬화하는 경우 아래 코드에 나열된 옵션과 같은 몇 가지 옵션을 설정할 수도 있습니다. JSON.parse 함수를 사용하여 JSON 문자열을 직렬화 해제하고 fromJSON 함수를 사용하여 아래 나열된 옵션으로 Spread 개체를 초기화하여 spread1과 일치하는 새 스프레드시트를 만듭니다.
