682 Pointshaving a little issue on the not operator.
initialScore = 8 initialScore += 1
let isWinner = !10
I know I'm making a mistake on the not operator. I have tried 3 different combinations. Anybody available to help, please?
// Enter your code below
var initialScore = 8
initialScore += 1
let isWinner = !10

let isWinner = initialScore != 10
Happy coding!
