JavaScript Arrays Challenge

Every time I submit this, I get "Your code took too long to run"

Question is:

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.

My answer is:

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

for (var i = 100; i > 10; i += 1) {
  console.log(i);
}

hi

for (var i = 100; i > 10; i += 1) {
  console.log(i);
}

that piece of code says to start at 100, and increment by 1 each loop as long as i > 10. but i starts at 100 right? therefore your stuck in an inifite loop. what you want to do is loop through each element in the temperatures array so first get the length of that. then each loop we access an element in the temperatures array (keeping in mind arrays start at 0). since arrays start at 0, we make i = 0 at first. we keep increasing the i counter as we access each element.

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

for (var i = 0; i < temperatures.length; i += 1) {
  console.log(temperatures[i]);
}

let me know if you have any questions
