Javascript ES6 Destructuring 디스트럭처링 (분해하기)

//Destructuring
let data = ['mac','apple','ms','samsung'];
let [myCom, ,yourCom] = data;

console.log(myCom, yourCom);	//mac ms

//Destructuring Object
let obj = {
    name : 'Jacob',
    address : 'S.Korea',
    age : 32
};

let {name,age} = obj;
console.log(name,age);	//Jacob 32

let {name:myName, age:myAge} = obj;
console.log(myName,myAge);	//Jacob 32


//Destructuring JSON Parsing
var news = [
    {
        "title" : "SBS",
        "imgurl" : "www.naver.com",
        "newslist" : [
            "A News.....",
            "B News....",
            "C News...."
        ]
    },
    {
        "title" : "KBS",
        "imgurl" : "www.daum.com",
        "newslist" : [
            "D News.....",
            "E News....",
            "F News...."
        ]
    }
];

let [,KBS] = news;
console.log(KBS);   //{title: "KBS", imgurl: "www.daum.com", newslist: Array(3)}

let {title,imgurl} = KBS;
console.log(title,imgurl);  //KBS www.daum.com

let [{title:titleSBS,imgurl:imgurlSBS},] = news;
console.log(titleSBS,imgurlSBS);  //SBS www.naver.com

function getNewsList([ ,{newslist}]) {
    console.log(newslist); 	//["D News.....", "E News....", "F News...."]
}
getNewsList(news);
