JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Iterating through an Array

I don't understand the question. What should I try to be doing here? Log into the console each one of the array values?

Can someone explain it to me?

script.js 
var temperatures = [100,90,99,80,70,65,30,10];
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">

<body>
<script src="script.js"></script>

I would recommend just using the for loop to log out each item like this.

for (var i = 0; i < temperatures.length; i++) { console.log(temperatures[i]); }

BTW: ++ in JavaScript, as well as many other programming languages, is an increment operator, i++ means increment i by 1, it's a shorthand for i = i + 1.

Thanks for the help Charlie! Got it done! The strange part is I think I was already doing that. I did: for (var a = 0; < temperatures.length; a += 1) { console.log(temperatures[a]); }

Always got a parse error. Figures...

Hey Rapha! Yes the challenge asks you to loop thru every item in "temperatures" and then log that item to the console!
