      arrayCounter(input) {
        if (typeof input === "undefined" || typeof input === "string" || typeof input === "number") {
          return 0;
        }
        else {

         return input.length;
        }
      }

Hi,

You forgot the "function" keyword before arrayCounter.

Thanks so much, Hugo. Stupid mistake.
