5,965 PointsChallenge Task for Return Values
Help me out with process in Treehouse - when I get stuck, like I currently am, I don't see where I can get advice, or hints ... I'm just left flat out stuck. I don't get what I should do, so I end up halting entirely instead of getting assistance to get over something I initially don't get. Am I missing something in Treehouse for learners that would address this gap? Thanks!

function arrayCounter (array) {
if (typeof array === 'undefined' || typeof array === 'string' || typeof array === 'number') {
return 0;
}
return array.length;
}

10,972 PointsThe forums are you best help. People usually answer pretty quick. Also another thing is, a lot of the challenge questions have already been asked by someone, so just copy the question you are stuck on, and paste into google and more than likely you will find that its been asked and you can see the answer

Full Stack JavaScript Techdegree Student 36,760 PointsI am having trouble with this challenge, also.
here is what I have so far:
function arrayCounter(x) { if (typeof x === 'undefined') { return 0; } if (typeof x === 'string') { return 0; } if (typeof x === 'number') { return 0; } if (typeof x === 'array') { return x.length; } }

Full Stack JavaScript Techdegree Student 36,760 PointsYou can't use typeof with "array" I had to use the following code:
if (typeof array === 'object') {
return array.length;
