   /* Write a JavaScript program that does each of the following things:

Defines a function called weirdArraySort() that accepts an array as an argument. This array may contain a mixture of single character strings and numbers. For example, this list would be valid input: [‘A’, 3, ‘X’, 1, ‘Q’]
Returns an array of letters sorted in reverse alphabetical order, followed by numbers sorted in ascending order. In the above example, the returned array would be: [“X”, “Q”, “A”, 1, 3]

    else {
