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

Question regarding Loops and Arrays

Hey Guys,

Please have a quick look at my code and tell me what is wrong. Been spending a bit of time on this and am struggling to understand the concept.

Question is : Use a for or while loop to iterate through the values in the temperatures array from the first item -- 100 -- to the last -- 10. Inside the loop, log the current array value to the console.

Cheers

script.js 
var index;

var temperatures = [
  100,
  90,
  99,
  80,
  70,
  65,
  30,
  10
];

for (index = 0; index < temperatures.length, index += 1) {
  console.log(temperatures[index]);
}
index.html 
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JavaScript Loops</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>

Hi, Corey Edwards there's a small syntax error here.

index < temperatures.length,

You should put a semicolon ; instead of comma , after the temperatures.length.

Other than that, your code is fine.
