addStars

Language/Type: JavaScript arrays

Write a function named addStars that accepts as a parameter an array of strings, and modifies the array by placing a "*" element between elements, as well as at the start and end of the array.

For example, if the array arr contains ["the", "quick", "brown", "fox"], the call of addStars(arr) should modify it to store ["*", "the", "*", "quick", "*", "brown", "*", "fox", "*"].

If the array passed is empty, you should add a single "*" to the array, resulting in ["*"].

Function: Write a JavaScript function as described, not a complete program.
