How do I log array items in order?

This one has me stumped. I am apparently not logging to the console in order? Any help appreciated! Thanks!

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

for (var i = 0; i < temperatures.length; i += 1) {
    console.log(i);
}

You are really close!

Just remember that in addition to having the index value [i] built into the loop, you also need to put the variable name inside of the method too.

Something like...

console.log(variable name[index value]);

Got it?

That's it! Thanks!

console.log(temperatures[i]);

That gives you a pass, but it isn't reliable as it prints them in reverse order. I tried using temperatures.sort() but this result is unreliable as well: [10, 100, 30, 65, 70, 80, 90, 99]. As you can see 100 is placed before 30. I haven't delved too far into ES6 yet, but after further research a function could sort them in order. But this is getting ahead of where we need to be with this exercise..
