Need some help with this challenge please

Here is the objective

Use a for or while loop to iterate through the values in the temperatures array from the first item -- 100 -- to the last -- 10. Inside the loop, log the current array value to the console.

Here is my code

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

function print(message){ console.log(message); } function printList(list){ var listHTML = '<ol>'; for (var i = 0; i < list.length; i += 1) {listHTML += '<li>' + list[i] + '</li>';

print(listHTML);

}

listHTML += '</ol>'; } printList(temperatures);

And here is the error

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.

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

function print(message){
  console.log(message);
}
function printList(list){
  var listHTML = '<ol>';
for (var i = 0; i < list.length; i += 1)
{listHTML += '<li>' + list[i] + '</li>';

   print(listHTML);

}

  listHTML += '</ol>';
}
printList(temperatures);

Just figured it out. I added lots of unnecessary code thinking it would order it. All I needed to do was log [i] as the index to the array temperatures out to the console.

Yep, you were working way too hard. :see_no_evil:

For best results with the challenges, follow the instructions carefully and don't do anything they don't specifically ask for.
