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('').
const reverseString = str => [...str].reverse().join('');
reverseString('foobar'); // 'raboof'
