title: Destructuring Arrays
|
|
---
|
|
|
|
# Introduction
|
|
|
|
Destructuring [arrays](20200826201029-arrays) was introduced in
|
|
[ES6](20201030093404-es6).
|
|
[Iterables](20201103112001-destructuring_iterables) can also be
|
|
destructured via the same principle.
|
|
|
|
# Syntax
|
|
|
|
``` javascript
|
|
const [, year, month, day] =
|
|
/^(\d\d\d\d)-(\d\d)-(\d\d)$/
|
|
.exec('2999-12-31');
|
|
|
|
console.log(`${year} ${month} ${day}`) // 2999 12 31
|
|
```
