Then give the loop a code body to control (braces instead of a semicolon). Inside the body, put the log statement to log only the current item. Use indexing (brackets) and the loop variable to select the current item from the array.

Full Stack JavaScript Techdegree Graduate 14,976 Pointsthis was the question; 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.
