Stuck on Iterating through arrays challenge

Not doing something right to console log my list. Hints would be nice. Am I trying to make it too simplistic?

script.js 
var temperatures = [100,90,99,80,70,65,30,10];
for (i = 0; i < temperatures.length; i ++);
 console.log(temperatures);

Your for loop isn't done correctly. You need to have an opening and closing curly brace, and that ; at the end of the for condition is unnecessary.

Thanks for the help. I must have been too tired to see my error, yesterday. It worked perfectly as soon as I added the curly braces and added back in the [i] in the console log.

First of all, you need squiggly brackets after if ().

You're really close but missing something. Try the following code:

var temperatures = [100,90,99,80,70,65,30,10]; for (i = 0; i < temperatures.length; i ++) { console.log(temperatures[i]); }

You need the square brackets [i] in order to know which array item you want to print to the console. I hope I could help.

Thanks Margarita. I had the [i] in at one time and it didn't work, so I took it out. I forgot to add it back in when I asked my question. It was the curly braces I was missing. Sometimes something is so obvious you can't see it (like a huge syntax error!).
