9.1.7 Checkerboard V2 Codehs ~upd~ -

The goal is to create a grid where the colors of the squares alternate like a traditional checkerboard. Unlike the first version of this exercise, "V2" usually requires a more dynamic approach—often utilizing variables for row and column counts or specific helper methods to determine which color should be placed at a specific coordinate. The Logic Behind the Grid

. To fill a 2D space, the program must iterate through rows and columns. Outer Loop: 9.1.7 Checkerboard V2 Codehs

// Constants for easy modification (Always use constants in V2!) const BOARD_SIZE = 400; const SQUARE_SIZE = BOARD_SIZE / 8; // 50px const COLOR_A = "red"; const COLOR_B = "black"; The goal is to create a grid where

: Always use SQUARE_SIZE instead of typing 40 everywhere. This makes it easy to change the board's density later. To fill a 2D space, the program must

// Determine color using the alternating pattern if ((row + col) % 2 === 0) square.setColor(COLOR_A); else square.setColor(COLOR_B);

9.1.7 Checkerboard V2 on CodeHS is more than just a drawing exercise. It teaches you – how to break a repetitive visual problem into a compact, logical set of instructions.
