Question
This assignment is graded based on correctness and will require you to use higher-order functions to sort automobiles. The description is below. You must make use of higher-order functions to sort the cars. You should not, for example, create entirely separate functions each with dedicated loops to sort the cars. You will need a loop (or potentially more than one loop depending on your sorting algorithm of choice) in the sortArr function but that is pretty much it. Use prototype whenever needed.
