 // Exercise 4
 // Consider this variable:
 var numbers2 = [2, 4, 6, 8, 10]
 // Write the code that will add the number 0 to the beginning of the original array.

 // Exercise 5

 var numbers3 = [2, 13, 6, 8, 4, 2]
 // Write the code that finds the index of the first appearance of the number 2.

 // Exercise 6
