getValues()

getValue is a function that listens for a string entered using the JS HTML DOM, ensures that the class invisible is added to the alert box, and then executes two more functions: reverseString and displayString.

---

reverseString()

reverseString is a function that uses a for loop to get the last item of the userString array (the user input), and then add it to the reverseString array until the index is less than zero.

---

displayNumbers()

displayString is a function that displays the reversed string using the JS HTML DOM and removes the class invisible from the alert box.
