Log the current array value. Not sure how to solve this one.

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

Okay, so what they are asking you to do is loop through the "temperatures" array and print each value to the console.

First we need to declare the variable "i" in our for loop,

Then, remember, arrays start at index '0'

Then, you can either count the number of items in the array manually, or you can use the in built array method "array.length" to get the total number of items in the array.

Then we want to increase the value of "i" each time we "loop" through which can be written as "i++"

Last thing we want to do is print the value of the "temperatures" array at index "i" which can be written as "temperatures[i]

So, if we want to loop through from the start of the array at index 0 to the end of the array("temperatures.length"),

We could write that as:

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

hope that helps!
