stuck on the last part of for loop

I am stuck on how to go about incrementing or decrementing var i. Since the temperatures do not decrease and increase at a constant rate, I am stuck on what to add to the last part of my for loop.

Thanks in advance for the help!

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

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

You've almost got it, but you need to increment i by one each time you run through the loop, and instead of logging current[i] you need to log temperatures[i], because there is no array named current. 

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

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

ahh i see! i was confused by the actual values of the temperatures. i forgot that the i only refers to the index number of each temperature. thank you very much!
