Challenge Task 1 of 2
Let's assume we're creating a silly game. In this game every time a user completes an objective (whatever it is) we increment their total score by 1 point.
In the editor below, initialScore is the players current score. Assuming they completed a single objective for this level, let's add 1 point to their score using the increment operator and assign the result to a constant named totalScore.
Remember that the position of the unary increment operator matters. For this task to pass, we want both totalScore and initialScore to have the same value after the increment operation.
// Enter your code below
var initialScore = 8
var totalScore = 8
let totalScore = totalScore + 1
let totalScore 9

Treehouse Moderator 37,862 PointsThe code you wrote is not following the DRY principal (Don't Repeat Yourself), you would have to write that same code with different numbers each time the player scores a hit. Also, you need to use a unary operator, not a binary operator.
var initialScore = 8
let totalScore = ++initialScore
