Return values stage 5

Can someone tell me what I am doing wrong here. I have been at this for a while and all I get is a parse error.

function arrayCounter (myArray) {
        if (typeof myArray ==== 'undefined', typeof myArray === 'string', typeof myArray === 'number')
        {

          return 0;
        }
       return myArray.length;
        }

Hi Jose,

You are very close. You need to remove the commas in the if conditional and replace them with a or statement (||). Commas in a if conditional have no meaning in javascript. Here is the code if you still need help.

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

Hope that helps.

I have this for that same exercise.

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

The terminal tells me it is a parse error of the syntax kind.
