JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Iterating through an Array

Please help | for loop with an array | Can't get it to log in order.

I can't figure out how to get it to output to the console "in order". I thought 0 would match the first item in the array 100 and then if I add 1 it would do the following until it completed the temperatures.length.

Any thoughts? Code is in scrips.js and is attached to this post.

Thank you in advance!

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

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

Your loop is correct but what you are logging is not. You are logging i when you should be logging the temperature at position i.
