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

NodeList to Array:

var headings = [ ... document.querySelectorAll('h1') ];Unique Arrays:

[ ...new Set(array) ]

Destructuring:

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

Swap like a snake:

[a,b] = [b,a]

Max in array?:

Math.max(...array);

List comprehension:

[ for (value of ["Harriet", "178"]) value ].join(" was "); // Would give us "Harriet was 178" // BTW it was Charles Darwin's tortoise.

_map?

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

Object.isz!

let Object.isz = (x, y) => x === y || Object.is(x, y); //^ Credits to Mark S. Miller.

Is it a hidden file?:

isHidden = (file) => /^\.|~$/.test(file); isHidden(".DS_STORE") // true

Repeat with me:

(0/0+"").repeat("7")+ " BatMan!" // "NaNNaNNaNNaNNaNNaNNaN BatMan!"

If you are using some, please do let me know!

Hope it blew your mind! ;)
