for (var i = 100; i >temperatures.length; i-=1) { console.log ( temperatures [i] );

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

 console.log ( temperatures [i] );

The challenge is to "iterate through the values in the temperatures array" but the loop starts the index at 100 and there are not that many values in the array.

The instructions also say to go "from the first item ... to the last" and the index is counting down. But the index of the first item would be 0, and it would need to go up to reach the last.
