Correct: `Array.from()` (it’s a static method) Incorrect: `Array.join()` (doesn’t exist; it’s a prototype method) This patch uses the common `#` syntax to denote `.prototype.`.

### everyNth
|
|
|
|
Returns every nth element in an array.
|
|
|
|
Use `Array.prototype.filter()` to create a new array that contains every nth element of a given array.
|
|
|
|
```js
|
|
const everyNth = (arr, nth) => arr.filter((e, i) => i % nth === nth - 1);
|
|
```
|
|
|
|
```js
|
|
everyNth([1, 2, 3, 4, 5, 6], 2); // [ 2, 4, 6 ]
|
|
```
