Sorting an array

Why is my code not working? I was not trained to sort an array before but I used the w3schools.com site to find this .sort attribute. Not working unfortunately..

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

for (i=0; i<temperatures.length; i+=1) {

I would not suggest using w3school for ANY help on programming. I would suggest you use MDN as a resource. The issue you are have is the answer is looking for you to iterate to the console the numbers. I would remove the sort method and log the iteration of the variable.

Thanks. But I am not yet there:

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

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

you are really close, you forgot you need to call the variable inside the console.log and you need to use the square brackets to pass in the iteration variable [i].
