To start with you're missing a few things in your for loop. You'll want to use i as an index value for the temperatures array. The first index value is 0. You got the second value, when i is less than temperatures.length. Lastly, you forgot to increment i each iteration of the for loop, using i++ or i += 1.

Next, the challenge wants you to log each value of the temperatures array to the console. To do this you will use the index value of i to access each value of the array using temperatures[i].

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

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

Hopefully this answers your question! :smile:
