JavaScript JavaScript Loops, Arrays and Objects Tracking Multiple Items with Arrays Iterating through an Array

Need Help on the For Loop with an Array Challenge.

I have re-watched the video and finally after feeling like I was going crazy, I looked for the answer on treehouse. I feel like my answer matches the "correct" answer that I have seen but I get a parse error, and I don't really know what that means. Maybe it's a glitch in treehouse and I actually did know what I was doing? XD

script.js 
var temperatures = [100,90,99,80,70,65,30,10];
for(var i = 0; i < temperatures.length; i += 1;){
console.log(temperatures[i]);
}

The issue is maybe with the semicolon after 1. You don't need it there

Try this one, make the the third i to (i++) not +=1

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

Thank you guys, the problem was the semi colon after 1.
