# not sure I understand this question on arrays

need a little help

script.js
```var temperatures = [100,90,99,80,70,65,30,10];

function new(num){
for (var i = 100; i < temperatures.length i += 1){
console.log(num);
}
}

Hi James

No need for the function, you just need to loop through each of the array items getting the array index value.

Without a loop this would look something like this:

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

console.log(temperatures[0]);
console.log(temperatures[1]);
console.log(temperatures[2]);
console.log(temperatures[3]);
// etc
```

However, the question is to do that in a loop with either a for loop or while loop. This can be done by looping over the array length and console logging each iteration, like below:

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

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

Alternatively, using a while loop, it would look like this:

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

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

Notice that each of the examples i provide follow a similar pattern:

1. a variable is set to iterate over `i`
2. a conditional is made to check if the iteration variable is less that the array length `i < temeratures.length`
3. After each console log, the iteration variable is incremented by 1 `i++`

Both of these loops are identical in there output and both do the exact same thing, but are syntactically different.

Hope this helps!
