JavaScript JavaScript Foundations Functions Return Values

Need help with challenge!

Hi, I have been unable to pass the challenge for return values in Javascript stage 5 (teamtreehouse.com/library/return values) I am using the code function arrayCounter (Array) { if (Array === "string", "number", "undefined") { return 0; } return Array.length; } I can't seem to find the proper coding to get past the error stating "if I pass in an array I get 0 not 3"

A hint to help with severe mental block. I have rewatched the lead in vids several times and can't seem to grasp the missing component!

Thanks a bunch!

Hi SL,

To begin with, don,t capitalize Array. Also, Javascript needs to know the typeof array being compared (ie. typeof array === "string"). And you have to explicitly say typeof every time you compare another type ( ie. "number"). Also in the if statement you need to use the or || operator in between each typeof comparison.
