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

The variable "temperatures" lenght (which is 8 in this case) is not more than or equal to 100! So your code will never run! Ask yourself, is the variable length is more than 0? In this case, is 0 < 8? Yes, it is! It adds +1 to 0 and the loop continues, Is 1 < 8? Yes, it is! And so on.. Until!, it becomes falls! Then we console the array.
