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

Oh no! There was a communication problem.

This has been the message for 2 days as I have tried to complete a javascript code challenge. Tried emailing tech support. They told me to disable plugins. Did that and it did not fix the issue. Lost an entire day of studying. Any other ideas?

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

Your code contains an infinite loop.

Your for loop is decrementing the counter variable by 10 every time the loop runs. This causes the loop to become infinite; it will run until the script fails since the exit condition will never be true.

This is the error:

i += -10

To fix this, you should increment the counter variable by one every time the loop runs. This will provide you with the expected results.
