Not sure what i'm doing wrong... should the i in console.log be different, i tried parenthesis

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

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

You're trying to log the index, not the temperatures.

If you really wanted to log the index you'd need parentheses instead of brackets. But what you want here is to log the temperature associated with each index, so you should subscript the temperature using the index in brackets:

  console.log(temperatures[i]);

Hi, Gena.

The reason that your code is not working is because you should use parenthesis and you should use your array to get the value out by using the index like this yourArray[i]. The correct code can be seen below. 

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

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