What is the challenge?

I don't understand what it is asking me to do.

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

}
index.html 
<!DOCTYPE html>

Let's break it down:

Use a for or while loop :point_left: You have that part
to iterate through the values in the temperatures array :point_left: you'll be looking in that array
from the first item -- 100 -- to the last -- 10 :point_left: give your "for" an index that runs to the length of the array
Inside the loop, log the current array value to the console. :point_left: call "console.log" on each array value

Does that help?

Hey Spencer!

You have to create a simple for loop which console-logs through each value in the temperatures array. Here's the structure of a basic for loop:

for( var i = 0; i < /* name of your array */.length; i++) {
  console.log(/* name of your array */[i]);
}

Hope this helps!
