How to check if an array value is a number

So what the challenge is looking for is a function that checks to see if the parameter passed into the function is an array. So what you need to do is use the "typeof" method to check to see if the parameter is a string, number or undefined. If the parameter is one of those you need to return 0, and if it's not then you need to return the length of the array. Try this code:

var arrayCounter = function(x){
    if(typeof(x) == "object"){
        return x.length;
    }else{
        return 0;
    }
}

If you notice, when I used the typeof method I didn't use "array". This is because in javascript, typeof(array) will return "object" not "array". So when checking to see if something is an array you need to compare it to the string "object". It's just one of those weird things about the language. Hope this helps.

i'am so stuck on this i dont know what im doing wrong

function(arrayCounter){ if (typeof arrayCounter === "string") { return 0;} else if(typeof arrayCounter === "name"){ return 0; } else if(typeof arrayCounter === "undefined"){ return 0; } else {return arrayCounter.length;}

  }

function(arrayCounter){ if (typeof arrayCounter === "string") { return 0;} else if(typeof arrayCounter === "name"){ return 0; } else if(typeof arrayCounter === "undefined"){ return 0; } else {return arrayCounter.length;}

  }
