Reverse alphabetically sorted strings in JavaScript

We are required to write a JavaScript function that takes in a lowercase string and sorts it in the reverse order i.e., b should come before a, c before b and so on.

For example:

If the input string is −

const str = "hello";

Then the output should be −

const output = "ollhe";

The code for this will be −

const string = 'hello';
const sorter = (a, b) => {
   const legend = [-1, 0, 1];
   return legend[+(a < b)];
}
const reverseSort = str => {
   const strArr = str.split("");
   return strArr
   .sort(sorter)
   .join("");
};
console.log(reverseSort(string));

Following is the output on console −
