surely aslong as the array starts printing from position 0 this should work?

Bummer: The items in the array weren't logged out in order. Your should log all the temperatures in order, starting at 100 and ending at 10.

is my error , im not sure how its skipping an item on the array .

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

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

Looks like you need to sort your array before logging them out.

You are logging i when you should be using i as an index to log the temperatures

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

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

can someone explain as to why adding the array [i] after temperatures in the console.log works and not just console.log(temperatures) by itself? To me, it seems like it would just log the index value (0,1,2,3, etc..) and not the values ( 100, 90, 99, etc..). confused

i was overthinking it and thought that we would have to create a separate variable such as 'list' like the previous video. thanks in advance!
