for (let row = 0; row < 8; row++) let rowArray = []; for (let column = 0; column < 8; column++) row > 4) if ((row + column) % 2 == 0) rowArray.push(1); else rowArray.push(0);
Hardcoding the size of the squares is a common mistake. CodeHS provides the canvas width and height globally via getWidth() and getHeight() . Because a checkerboard is a perfect square grid, you calculate the size of a single square like this: javascript 9.1.6 checkerboard v1 codehs
The modulo operator ( % ) checks for a remainder when dividing by 2. A remainder of 0 means the sum is even, triggering COLOR_ONE . Common Mistakes to Avoid for (let row = 0; row < 8;
else if (col % 2 == 0) putBeeper();
if (frontIsClear()) move(); else break;
// Optional: return to start turnAround(); while (frontIsClear()) move(); A remainder of 0 means the sum is even, triggering COLOR_ONE
In this specific CodeHS exercise, you typically edit the file named Checkerboard.java . You are expected to fill in the logic inside the nested for loops to set the color of the Rectangle objects stored in a 2D array.
