sample Data

 

let swCho = {
    name : 'swCho',
    age : 28,
    likes : {
        computer : 'js, java, web, algorithms',
        respects : 'feyman, Jaeseung Jeong, egoing ..',
        movie : 'The Spiriting Away Of Sen And Chihiro'
    }
} 

 

// Object to JSON
// stringify(obj)

let json = JSON.stringify();
json = JSON.stringify(true);
console.log(json);

json = JSON.stringify(['apple', 'banana']);
console.log(json);

let swCho = {
    name: 'swCho',
    beMad: () => console.log("뿌잉뿌잉 ><"),
    curAge: (new Date()).getFullYear() - 1993 +1,
    toDay: new Date()
    //,symbol: Symbol('id')
};
json = JSON.stringify(swCho);
console.log(json);

// js만의 특별한 dataType이나 메서드는 포함이 안댄다

 

json은 string 타입이야.

 

// JSON to Object
// parse(json)

console.clear();
json = JSON.stringify(swCho);
let obj = JSON.parse(json);
console.log(obj);
swCho.beMad();

console.log(swCho.toDay.getDate());

 

역..과정

​

나머지는 낼~모래 다시 하자...
