538 PointsThis is a bit confusing. I'm trying to work off of what the video was talking about, but i'm finding myself confused.
I just need this to be explained to me.
// Enter your code below
var initialScore = 8
var totalScore = initialScore
totalScore += 8

Treehouse TeacherI'm taking for granted here that you're stuck at step one. Ok so let's say the user is playing a game, but they saved and exited. When they come back in they pick up with their original score which at this time is 8 points. Now they do something which earns them a new point! So what we want to do now is set both the initial score and the total score to the same number. And we do that like this:
var initialScore = 8
let totalScore = ++initialScore
This takes the inital score and increases it to 9 and then assigns 9 back into total score. Both scores are identical. However, if we try to do it like this:
var initialScore = 8
let totalScore = initialScore++
This will be incorrect. What actually happens in this case is that first the initial score which is 8 is assigned into totalScore and then the initial score is incremented. This means that the total score would just have a value of 8 while initial score would have a value of 9. Hope that makes sense!
