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.`.

### take
|
|
|
|
Returns an array with n elements removed from the beginning.
|
|
|
|
Use `Array.prototype.slice()` to create a slice of the array with `n` elements taken from the beginning.
|
|
|
|
```js
|
|
const take = (arr, n = 1) => arr.slice(0, n);
|
|
```
|
|
|
|
```js
|
|
take([1, 2, 3], 5); // [1, 2, 3]
|
|
take([1, 2, 3], 0); // []
|
|
```
