need help writing a function, maskify, which: Takes a string or number and changes all but the last four characters into '#'. The function should return a string. hint javascript Of course, we’ll have to use a loop. We could loop from the beginning to end or the other way around (right to left), it doesn’t much matter. But the most important piece to figure out in this loop: How do we know when we’re in the last 4 characters, and when we’re not in the last four characters. Remember, to find the last character in a string/array, we use someStr.length - 1. We can use the same to find the 2nd-to-last character by using someStr.length - 2 and so forth.
