script.js 
var temperatures = [100,90,99,80,70,65,30,10];
for (var i = 10; i<temperatures.length; i+=1) {
    console.log(temperatures[i]);

Hi Simon

Just change the "var i = 10" to "var i = 0".

Hi Simon, you are close, just change variable i to 0. You use var i to access items from your array but there is no item at position(index) 10.

Here's the code:

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

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