Problem

You have an array and you need to remove anything that is not a number and double everything else.

Solution

$a = kdaviesnz/utilities/lists(\[null, "apple", 1,2,3\]);

$result = $a->filter(function($item) { return is\_numeric($item) } )->map(function($item) { return $item \* 2 } )()

$a\_parsed = $result()
