+At the start of the course, you worked in teams to sort your team members, labelled by
+numbers, in ascending or descending order.
+
+Today, you will be applying the sorting algorithm you used in that exercise in code! 
+
+Create a function called sortAges which:
+- takes an array of mixed data types as input
+- removes any non-number data types without using the built-in javascript filter method
+- returns an array of sorted ages in ascending order 
+  - HARD MODE - without using the built-in javascript sort method 😎
+
+You don't have to worry about making this algorithm work fast! The idea is to get you to
+"think" like a computer and practice your knowledge of basic JavaScript.
