stringify

JSON.parse(): JSON 문자열을 JavaScript 객체로 변환

const obj = {
  name: "홍길동",
  age: 25,
  married: false,
  family: {
    father: "홍판서",
    mother: "춘섬",
  },
  hobbies: ["독서", "도술"],
  jobs: null,
};

const str = JSON.stringify(obj);

'{"name":"홍길동","age":25,"married":false,"family":{"father":"홍판서","mother":"춘섬"},"hobbies":["독서","도술"],"jobs":null}'

  const str2 = JSON.stringify(obj, null, 2);

  {
  "name": "홍길동",
  "age": 25,
  "married": false,
  "family": {
    "father": "홍판서",
    "mother": "춘섬"
  },
  "hobbies": [
    "독서",
    "도술"
  ],
  "jobs": null
}

각 속성에 접근이 가능하다.

• obj.name
  '홍길동'
• obj.age
  25
• obj.married
  false
• obj.family
  {father: '홍판서', mother: '춘섬'}
• obj.family.mother
  '춘섬'
