# ES6 One Liners to Show Off

> Collection of impressive ES6 one-liners for destructuring, spread, Sets, and more. Practical notes and code examples on ES6.

Here is a collection of ES6 one liners to show off!

## NodeList to Array

```javascript
var headings = [ ...document.querySelectorAll('h1') ];

## Unique Arrays
javascript
[ ...new Set(array) ]

## Destructuring
javascript
var {foo, bar} = {foo: "lorem", bar: "ipsum"};
// foo => lorem and bar => ipsum

## Swap Like a Snake
javascript
[a, b] = [b, a]

## Max in Array
javascript
Math.max(...array);

## Arrow Map
javascript
[{id: 1}, {id: 2}].map(x => x.id)
// [1, 2]

## Is it a Hidden File?
javascript
isHidden = (file) => /^\.|~$/.test(file);
isHidden(".DS_STORE") // true

## Repeat with Me
javascript
(0/0+"").repeat("7") + " BatMan!"
// "NaNNaNNaNNaNNaNNaNNaN BatMan!"
```

Hope it blew your mind! ;)
