A Challenge question

It tells me,

'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.'

Any suggestions?

script.js 
var temperatures = [100,90,99,80,70,65,30,10];
for (var i = 0; i < temperatures.length; i += 1) {
  console.log([i]);
}

Hi Immnuel,

you've done everything correct apart from declaring the variable that holds the array data:

Your code:

var temperatures = [100,90,99,80,70,65,30,10];
for (var i = 0; i < temperatures.length; i += 1) {
  console.log([i]);
}

Updated Code:

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

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

You are near. Inside the console.log() use temperatures with [i].
