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

Using For Loop With an Array

Ok, so this exercise asks us to use a for or while loop to iterate through the temp values, then log the current value to the console. It's throwing a "syntax error: parse error." I'm baffled! Any help would be most appreciated.

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]);
}

There is a mistypeing in your code:

for (var i = 0; .....) not for (var i = 0, .....)

Use a semicolon instead of a comma after (var i = 0)

Thanks so much, Zoltán! Completely missed it. I'm not used to assigning variables within for loops yet.

Anywho, thanks again.
