Code Challenge

"or" characters are marked by two repeating "|" symbols placed between the two values. example:

''' 'this' || 'that' // evaluates to "this" or "that" '''

I also recently had to spend some time on that one and get some help. I will tell you that the biggest point after declaring your function is using the typeof() method to pass in your argument. here's a link to the forum help I got when I posted on this. Should clear things up for you (https://teamtreehouse.com/forum/cant-seem-to-get-this-right)

good luck

btw - the arguments don't need to exist outside the function. I saw an example where they did and it looked successful (the member created an array outside of the function and then passed it in and it accepted the answer), but I wanted to leave it open as if it was to accept an argument or parameter later on and it was just fine.

A method header needs to look like this:

function arrayCounter(parameters) {
//Code Goes Here
return something;
}

So the challenge wants you to make a function that takes a parameter than checks weather it is an array and execute one line of code, or execute another line if something else is true. Also remember that or in JavaScript is represented by ||. Moreover the length method is a property of an array. So it must be done on an array, like so: myArray.length

Hope this helps you figure it out good luck. And just comment if you have any further trouble with this challenge.
