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

| var headings = [ ... document.querySelectorAll('h1') ];
|
Unique Arrays:
Destructuring:
1
2
| var {foo, bar} = {foo: "lorem", bar: "ipsum"};
// foo => lorem and bar => ipsum
|
Swap like a snake:
Max in array?:
List comprehension:
1
2
3
| [ for (value of ["Harriet", "178"]) value ].join(" was ");
// Would give us "Harriet was 178"
// BTW it was Charles Darwin's tortoise.
|
_map?
1
2
| [{id: 1}, {id: 2}].map(x => x.id)
// [1,2]
|
Object.isz!
1
2
| let Object.isz = (x, y) => x === y || Object.is(x, y);
//^ Credits to Mark S. Miller.
|
Is it a hidden file?:
1
2
| isHidden = (file) => /^\.|~$/.test(file);
isHidden(".DS_STORE") // true
|
Repeat with me:

2
| (0/0+"").repeat("7")+ " BatMan!"
// "NaNNaNNaNNaNNaNNaNNaN BatMan!"
