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 −
