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.`.

### reverseString
|
|
|
|
Reverses a string.
|
|
|
|
Use the spread operator (`...`) and `Array.prototype.reverse()` to reverse the order of the characters in the string.
|
|
Combine characters to get a string using `String.prototype.join('')`.
|
|
|
|
```js
|
|
const reverseString = str => [...str].reverse().join('');
|
|
```
|
|
|
|
```js
|
|
reverseString('foobar'); // 'raboof'
|
|
```
