Even Numbers [3 marks] Create a function that determines if a provided number is even. Define an array of numbers, then on the array use the appropriate array iterator to determine if the array contains only even numbers using the function you defined. Output the results, and test with several arrays. Long Names [3 marks] Define an array of names. Use an iterator to retrieve a new array containing only the names longer then 12 characters. Your iterator should be passed an anonymous arrow function.
