Tracking Multiple Items with Array: Code Challege

Hello I have been having trouble with my code in the following challenge:

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

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

I had to use a for or while loop to iterate through the values in the array from the first item to the last item. When I typed out my loop I got an error message saying "TypeError : 'undefined' is not an object (evaluating 'console.log._args[i]'). I am completely stumped.

Thank you so much. I have solved it just a minute ago by changing the 7 to an 8 to log all of the numbers in the console.

Hi Phillip,

You have a typo in your for loop. temperatures.legnth should be temperatures.length
