What am I doing wrong??

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

function printList ( list ) {
  var listHTML = "<ol>";
  for ( var i = 0; i < list.length; i += 1) {
    listHTML += "<li>" + list[i] + "</li>";
   }
   listHTML += "</ol>";
   return listHTML;
}

console.log(printList(temperatures[i]));

this prints out in the console, but didn't get accepted as the correct answer.

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

function printList ( list ) {

for ( var i = 0; i < list.length; i += 1) { sp += list[i] + " "; }

return sp; }

console.log(printList(temperatures));

Creating a function in this case is a bit of overkill. Decent practice I assume but if you want it to be simplified remove the function and do something like this: var temperatures = [100,90,99,80,70,65,30,10]; for (var i=0;i<=temperatures.length; i++){

console.log(temperatures[ i ]);

}
