3,016 PointsWhat does this question mean? What is it trying to ask?
"Use a for or while loop to iterate through the values in the temperatures array from the first item -- 100 -- to the last -- 10."
Ok so what is it asking me to do..?
var temperatures = [100,90,99,80,70,65,30,10];
for ( i = 0; i < temperatures.length; i += 1; ) {
console.log(temperatures.length);
}

You can access the current array value by using the index represented by your "i" variable:
temperatures[i]
Hope that helps, you're pretty close.

You have a couple of very minor mistakes in your code which are:
- You have a semi-colon after
i += 1which causes a syntax error, the last statement in conditions do not require a semi-colon - You are logging the length of the array for every temperature, instead you need to select the temperature using the
ivariable declared in the loop
var temperatures = [100,90,99,80,70,65,30,10];
for ( i = 0; i < temperatures.length; i += 1) {
// i = the current index starting from zero
console.log(temperatures[i]);
}
Happy coding!

3,016 PointsOk so I re-attempted the challenge and passed it, but I still don't fully get it. So first, we are testing to see whether the counter is less than the length of the items within the array, it is because by default it holds a value of 0, so it adds one to counter, then the log function logs 1 in the index of the array to the javascript console, the loop repeats, but now since counter has a value of 1, it'll add 2, and the index will change to 2, and it'll log the index of 2 to the console, whicn is 99, so forth and so on. Until the loop ends. Is that right?
