Why am I wrong?

This is the code I have tired and read over several times, I am not sure why or how I am wrong and would love someone to point me in the right direction.

function arrayCounter (array) {

        if (typeof array === "undefined", "string","number") {
          return 0;
        }
    console.log(array.length);
      }

Andrew,
You're close. First when you are checking the typeof, that needs to be 3 separate checks separated by the "or" operator ( ||), not a comma separated list.
Second, make sure you are returning the length of the array so that it could be used by another function. Logging the value to the console, does just that. It logs it, but doesn't make it accessible if someone was trying to call the arrayCounter function. Just like you returned the value of 0, make sure you return the length.
