9.1.7 Checkerboard V2 Codehs -

A checkerboard is defined by a simple mathematical rule: A square’s color is determined by the parity (even/odd) of the sum of its row and column indices.

If (row + column) % 2 == 0 → Color A.
If (row + column) % 2 == 1 → Color B. 9.1.7 Checkerboard V2 Codehs

This is the secret sauce. Memorize this rule – it is the heart of the 9.1.7 exercise. A checkerboard is defined by a simple mathematical

Bad Code:

if (row === 0 && col === 0) square.setColor("red");
if (row === 0 && col === 1) square.setColor("black");
// ... 62 more horrendous lines

Fix: Use the (row + col) % 2 formula. Never hardcode each tile. Fix: Use the (row + col) % 2 formula

The goal is typically to draw an 8x8 checkerboard with alternating black and red squares (or another color pair).
