JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Iterating through an Array

Need some assistance..

use a for or while loop to iterate through the values in the temperatures array from the fist item 100 to the last item 10. inside the loop log the current array value to the console.

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

Hi Tim,

You're really close! Think about what the code should be doing each time through the loop. With temperatures being an array of length 8, the loop will iterate eight times through indexes 0 - 7.

Do you remember how to get a value from an array at some index? The index is changing each time in the loop with the variable i being incremented, which will allow you to index into the array and pull out a value. So, instead of printing out all the values of the temperature array - each loop iteration - just print the value of the array at the i index.

I hope this was helpful, without providing an exact answer.

Best Regards
