JavaScript Searching and Sorting Algorithm: Alphabetically sorts the characters in a string
JavaScript Searching and Sorting Algorithm: Exercise-19 with Solution
Write a JavaScript program to sort the characters in a string alphabetically.
- Use the spread operator (...), Array.prototype.sort() and String.prototype.localeCompare() to sort the characters in str.
- Recombine using String.prototype.join('').
Sample Solution:
JavaScript Code:
const sortCharactersInString = str =>
[...str].sort((a, b) => a.localeCompare(b)).join('');
console.log(sortCharactersInString('cabbage'));
Sample Output:

JavaScript: Tips of the Day
How to insert an item into an array at a specific index (JavaScript)?
What you want is the splice function on the native array object.
arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:
var arr = []; arr[0] = "Jani"; arr[1] = "Hege"; arr[2] = "Stale"; arr[3] = "Kai Jim"; arr[4] = "Borge"; console.log(arr.join()); arr.splice(2, 0, "Lene"); console.log(arr.join());
