Destructuring 분해하다.

 

Destructuring Array

let data = ['crong', 'honux', 'jk'];
let [jisu,,jung] = data;
console.log(jisu, jung); // 'crong', 'jk'

 

Destructuring Object

 let obj = {
  name : 'crong',
  address : 'korea',
  age : 30
}

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

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

 

Destructuring JSON

let [,mbc] = news;
let {title, imgurl} = mbc;
console.log(title, imgurl);

let [, {title, imgurl}] = news;
console.log(imgurl);
