Can't quite grasp this one for some reason. Can someone help me out here?

I need to iterate these variables in order from 100 to 10 but I found the code to be a bit confusing because I haven't worked in JS in a while and I don't quite understand the video explaining it. Can someone help me out here?

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

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

Hey there,

You're really close.

Instead of logging out just the value of the iteration variable (m), you need to log out the value in the array being iterated through. You use [] to access the index of the array, so it would be something like this: console.log(nameOfArray[index]).

I hope this helps! :)

Keep Coding! :dizzy:
