Help With Arrays

Around line 17, create a function named 'arrayCounter' that takes in a parameter which is an array. The function must return the length of an array passed in or 0 if a 'string', 'number' or 'undefined' value is passed in.

I srsly have no clue how to do this/

Hi Devin, I get through this challenge by this code:

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

Hi Devin,

I made a detailed answer in another thread about this as I believe it should have been explained the way I did in my reply. https://teamtreehouse.com/forum/stuck-on-stage-5-functions-quiz
