In the previous episode, I mentioned that there鈥檚 another way to calculate the difference that requires fewer lines of code - and that鈥檚 what you鈥檙e going to be doing in this challenge.

var difference = targetValue - sliderToInt
if (difference < 0) {
    difference = difference * -1
}
if (difference < 0) {
  difference *= -1 // Updated Code
}
