 // ==== Challenge 1: Use .forEach() ====

 // ==== Challenge 3: Use .filter() ====

 // ==== Challenge 5: Be Creative ====
 // Now that you have used .forEach(), .map(), .filter(), and .reduce().  I want you to think of potential problems you could solve given the data set and the 5k fun run theme.  Try to create and then solve 3 unique problems using one or many of the array methods listed above.

+// Problem 2
+//Find all the emails

+//Name and Donation
