* 3. Write a loop that logs the numbers 15 to 50 (inclusive) to the console.

1. What part of the for loop will allow you to access each indiv

2. What part of the for loop will need the array's length in ord

var arrayOfArrays = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]

} #Assignment - Forception
* This assignment will have you practice nested for loop logic by looping through two arrays simultaneously.
