This is what I've been trying to use, without any success...

function arrayCounter (name, surname, greeting) {
        if(typeof name === 'Dani') {
         return name.0; 
        }
        if (typeof surname === 'undefined') {
         surname = 'Manca'; 
        }
      }

Hi Daniele,

In this case, you should just passed in one argument to the function, which is an array. That doesn't mean you should add several arguments. Just one with the name "array" (for example) would be ok.

function arrayCounter (array) {
}

Next you can set a variable "returnValue" with the value "0". Its value will be returned at the end of the function. 

function arrayCounter (array) {
  var returnValue = 0;

  return returnValue;
}

Next you should just specify your conditions so that the value of the variable "returnValue" is accordingly modified. In that case we should be returning the length of the argument just in case it is an array. We can tell the function to keep its value "0" if it is a 'string' or a 'number' or 'undefined. The following code should work:

function arrayCounter (array) {
  var returnValue = 0;

  if (typeof array !== 'string' &&
     typeof array !== 'number' &&
     typeof array !== 'undefined') {
     returnValue = array.length;
  }

  return returnValue;
}

It is also a better practice to make your function return just once at the end. I hope it helped! Good luck with the following!
