JavaScript Object-Oriented JavaScript: Challenge Making the Game Interactive moveLeft() and moveRight() Methods Solution

moveRight() alternative, would this cause an issue?

 moveRight(){
        if (this.columnLocation < game.board.columns - 1) {
            this.htmlToken.style.left = this.offsetLeft + 76;
            this.columnLocation += 1;
        }
    }

I handled the column amount within my method rather than passing it as an argument. Tested and it works fine but just wondering it anyone can think of any possible issues with this solution?

I think I may of thought of one possible issue;

const game = new Game();

if the variable name for the game was changed in the app file then this solution would no longer be able to call this;

game.board.columns

as it would only search for a game with the variable name 'game'.

I think you've answered your own question! :+1:

You could, however, pass in the game object and still access the columns in the function:

moveRight(game){
    if (this.columnLocation < game.board.columns - 1) {
        this.htmlToken.style.left = this.offsetLeft + 76;
        this.columnLocation += 1;
    }
}
