In the iterating array question. What is the difference between using +=1 and 1 ++ I thought they were the same.

in the question below.

Use a for or while loop to iterate through the values in the temperatures array from the first item -- 100 -- to the last -- 10. Inside the loop, log the current array value to the console.

I had everything right but the 1 ++ I had +=. What's the difference?

There's really no difference in what these operators do, i++ increments the variable i by 1, whereas i += 1 adds whatever number is on the right side to the variable on the left.
