I'm having trouble logging the items in the array to the console in order from first parameter to the last.

I've tried nearly everything I could think of but the program tells me that the I'm not logging the numbers in order from first parameter on the left to the last.

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


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

I am a little confused by your question, but I am assuming you would like to output the values in the array from 10 sequentially to 100? if so, shift() would not be a good choice since it actually removes values from the 0 position in the list every time the loop runs. I would suggest if you want to output the sequential numbers to sort your list first then output the contents.

var temperatures = [100,90,99,80,70,65,30,10];
temperatures = temperatures.sort(function(a, b){return a-b});

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

The solution is a lot more complicated than I expected, thanks a lot.
