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.

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

You need to take and remove students.length and replace that with temperatures.length and do the same for the console log swap out the students with temperatures and it should work just fine.

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

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

why are you guys writting your code with the variable inside the for loop just like this var temperatures = [100,90,99,80,70,65,30,10];

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

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

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