Hi Shannon, The idea behind this one is to check if the arguments passed in are a string, number, or undefined first. If they are, return 0. Otherwise, return the length of the argument passed in (array.length). Perhaps the code is worth 1000 words. Let me know if you have any questions! Smile more, Laura :)

function arrayCounter(array) {
        if (typeof array == "string" || typeof array == "number" || typeof array == "undefined") {
            return 0
            } else {
            return array.length
            }
      }
