Hi Toni, First you need to create a function called arrayCounter which takes in an Array object. So your function should look something like this:

function arrayCounter(array)
{
}

The question also asks to return 0 if the parameter type is either a string, number, or undefined instead of an Array object.

So in your method body, you need to enter an if statement to check the input parameter. if(typeof array === "undefined" || typeof array === "string" || typeof array === "number")

Return a 0 if the condition of the if statement is true. Return the length of the array object if the condition is false.
