Missing function arrayCounter ??

I keep getting a message that I am missing a function called arrayCounter!!

What am I doing wrong? Here is my code...

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

Because you are using the double equal 

      function arrayCounter(parameter){
        if(typeof parameter === 'string' || typeof parameter === 'undefined' || typeof parameter === 'number'){
                return 0;
        }else{
                return parameter.length;
        }
      };

Here a couple of useful examples: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/typeof
