Somebody can see my code? I find it difficult to resolve.

How can I write an array as a parameter in a function?

Here is my code: 

 function arrayCounter ( **?** ) {
        if (typeof **?** === 'undefined') {
          return 0;
        }
        if (typeof **?** === 'number') {
          return 0;
        }
        if (typeof **?** === 'string') {
          return 0;
        }
        return **?**.length;
      }

Please, have a look at my code and help me! Thanks in advance! :)

You would pass an array to a function the same way you would pass any other parameter. Just name it param or something, like this:

function arrayCounter(param) {
   //code goes in here and you can access the array as param
}
