[JavaScript] Destructuring 배열 분해

DESTRUCTURING 

A short, clean syntax to 'unpack' : 

- Values from arrays

- Properties from objects

Into distinct variables. 

 

 

Array

const scores = [100, 98, 90 ,88, 53, 33];

const highScore = scores[0];
const secondHighScore = score[1];

const [gold, silver] = scores

> gold
< 100

> silver
< 98
