/**
 * Array – Exercise
 * 
 * Use only array instance methods!
 
 * 1. Filter arr1 to only contain only even values
 * 2. Reverse order the values of in arr1
 * 3. Combine both arr1 and arr2 together, then loop through each value and
 *    log each value to the console
 *
 * Bonus: Using Array.sort and a custom sorter function, sort arr2 by 
 *        length of value, descending
