I am stuck on a Code Challenge and not sure what I am doing wrong. Please help!
Challenge Question:
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.

The answer I provided is below:
var initialScore = 8 initialScore = initialScore + 1
var totalScore = initialScore totalScore = ++initialScore

Courses Plus Student 26,336 PointsHi Robin,
The chanllenge asks us to increment the value of initialScore by 1, and assign it to a CONSTANT totalScore. To achieve that, w'll do
var initialScore = 8
let totalScore = ++initialScore
As the increment operator is before the value initialScore, it firsts increments the value and then assigns it.
What you were doing wrong is creating a VARIABLE totalScore, assigning it the incremented initialScore, and then incrementing it again.
Hope I answered your question!

//heres the second part to the question not = to 10 they are the winner
