title: Sort an Array Alphabetically using the sort Method
challengeType: 1
---
## Description
The sort method sorts the elements of an array according to the callback function.
For example:
function ascendingOrder(arr) {
return arr.sort(function(a, b) {
return a - b;
});
}
ascendingOrder([1, 5, 2, 3, 4]);
// Returns [1, 2, 3, 4, 5]
function reverseAlpha(arr) {
return arr.sort(function(a, b) {
return a === b ? 0 : a < b ? 1 : -1;
});
}
reverseAlpha(['l', 'h', 'z', 'b', 's']);
// Returns ['z', 's', 'l', 'h', 'b']
Note: It's encouraged to provide a callback function to specify how to sort the array items. JavaScript's default sorting method is by string Unicode point value, which may return unexpected results.
## Instructions
Use the sort method in the alphabeticalOrder function to sort the elements of arr in alphabetical order.
## Tests
```yml
tests:
- text: Your code should use the sort method.
testString: assert(code.match(/\.sort/g), 'Your code should use the sort method.');
- text: alphabeticalOrder(["a", "d", "c", "a", "z", "g"]) should return ["a", "a", "c", "d", "g", "z"].
testString: assert(JSON.stringify(alphabeticalOrder(["a", "d", "c", "a", "z", "g"])) === JSON.stringify(["a", "a", "c", "d", "g", "z"]), 'alphabeticalOrder(["a", "d", "c", "a", "z", "g"]) should return ["a", "a", "c", "d", "g", "z"].');
- text: alphabeticalOrder(["x", "h", "a", "m", "n", "m"]) should return ["a", "h", "m", "m", "n", "x"].
testString: assert(JSON.stringify(alphabeticalOrder(["x", "h", "a", "m", "n", "m"])) === JSON.stringify(["a", "h", "m", "m", "n", "x"]), 'alphabeticalOrder(["x", "h", "a", "m", "n", "m"]) should return ["a", "h", "m", "m", "n", "x"].');
- text: alphabeticalOrder(["a", "a", "a", "a", "x", "t"]) should return ["a", "a", "a", "a", "t", "x"].
testString: assert(JSON.stringify(alphabeticalOrder(["a", "a", "a", "a", "x", "t"])) === JSON.stringify(["a", "a", "a", "a", "t", "x"]), 'alphabeticalOrder(["a", "a", "a", "a", "x", "t"]) should return ["a", "a", "a", "a", "t", "x"].');
```
