# 6.10. Sorting or Reversing an Array

## Problem

You want to sort the elements of an array.

## Solution

Use the `sort( )` method. For arrays of objects, you can also use the `sortOn( )` method.

## Discussion

You can perform a simple sort on an array using the ```sort( )``` method. The `sort( )` method, without any parameters, sorts the elements of an array in ascending order. Elements are sorted according to the Unicode code points of the characters in the string (roughly alphabetical for Western European languages). However, the sort is also case-sensitive, and it sorts numbers “alphabetically” instead of numerically. See Recipe 6.11 for details on creating custom sorting algorithms that are case-insensitive.

```words = ["tricycle", "relative", "aardvark", "jargon"];
words.sort(  );
trace(words);   // Displays: aardvark,jargon,relative,tricycle```

The `reverse( )` method reverses the order of the elements in an array:

```words = ["tricycle", "relative", "aardvark", "jargon"];
words.reverse(  );
trace(words);   // Displays: jargon,aardvark,relative,tricycle```

If you want to sort the elements of an array in descending order, use the `sort( )` method followed by the `reverse( )` method:

```words = ["tricycle", "relative", "aardvark", "jargon"];
words.sort(  );
words.reverse(  );
trace(words); // Displays: tricycle,relative,jargon,aardvark```

You can sort arrays of objects using the ```sortOn( )``` method. The `sortOn( )` method requires a string parameter specifying the name of the property on which to sort the elements:

`cars = new Array( ); cars.push({make: ...`
