In your for-loop, you have three parts to the statement. Initializing a variable, setting a condition, and setting the iterator. For your code, you set i to equal 100 whereas your condition only iterates through the loop while i is less than the size of the array temperatures (8). Because of this, the loop defaults to false and never loops through.

You also on Line 3, you reference the current item in the loop using parentheses. In Javascript, we reference a specific item in an array using brackets like this:

console.log(temperatures[i]) ;
