1,901 PointsHow do you check if the input parameter of your Function is an Array?
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.

42,016 Pointsyou could use the isArray function which returns True is a variable is an array, false if it isnt
if ( Array.isArray(someVariable) )
however you might want to take a look at this forum post for some other solutions. This challenge is pretty picky about what it determines is correct and what it determines is incorrect
