: Explicitly setting grid[i][j] = 1 for the required rows rather than just printing the final output. 2. Common Errors in Initial Attempts

In the CodeHS 9.1.6 exercise, "Checkerboard v1," students must create an : Program runs slowly, especially with larger board sizes

Before looking at the fixed code, it is vital to understand the mathematical pattern behind a checkerboard.

coordinate depends on the row index. Reversing these results in a diagonal line or a broken vertical stack instead of a grid. 2. Static Color Switching Reversing these results in a diagonal line or

var board = []; for (var i = 0; i < 8; i++) board[i] = []; for (var j = 0; j < 8; j++) if ((i + j) % 2 === 0) board[i][j] = "black"; else board[i][j] = "white";
