```// Solution:
// The optimal solution is to use the built-in reverse() method.
// This is optimal because it is a built-in method that is already optimized.
// It is also optimal because it is a one-liner.

function reverseString(str) {
return str.split('').reverse().join('');
}

console.log(reverseString('abcdef'));```
