Figure 6–32. Reversing the order of elements in an array by invoking its reverse() method
Sorting the Elements in an Array
CHAPTER 6 ■ FUNCTIONS AND ARRAYS
Though reversing the order of elements in pirates is interesting, it would be more helpful if we could
reorder those by wins or losses. To do so, we’d invoke sort() on pirates and pass a function value to do
the reordering work. JavaScript will pass that function two elements from pirates—yup, happens by
magic—and the function will then return -1 if the first element ought to come before the second
element, 0 if there is a tie, and 1 if the second element ought to come before the first element. Though
it’s typical for the function to return -1 and 1, any negative or positive integer will do. The only return
value set in stone is 0, which conveys a tie.
