Definition and Usage
The sort() method sorts the items of an array.
The sort order can be either alphabetic or numeric, and either ascending or descending.
Default sort order is alphabetic and ascending.
Note: When numbers are sorted alphabetically, "40" comes before "5".
To perform a numeric sort, you must pass a function as an argument when calling the sort method.
The function specifies whether the numbers should be sorted ascending or descending.
It can be difficult to understand how this function works, but see the examples at the bottom of this page.
Note: This method changes the original array.
Browser Support
The sort() method is supported in all major browsers.
