The most efficient way to "fix" a broken checkerboard script is using the formula (i + j) % 2 . This ensures that: get one value. Odd sums

: Incorrect conditional logic in the color assignment.

Most students fail this exercise because they hardcode a switching variable (like isBlack = !isBlack ) at the end of each cell. When a row ends, the next row starts with the wrong color, creating vertical stripes instead of a checkerboard. The Fixed Code javascript

The goal is to render a flawless check pattern without drawing outside the canvas boundaries. This guide walks through the logic, common errors, and the complete, fixed code solution. Understanding the Requirements function at the very end to display your

To build a flawless checkerboard pattern, you must calculate the value of a cell based on its unique mathematical coordinates: the and the column index .

for each row in range(rows): for each col in range(cols): x = col * square_size y = row * square_size if (row + col) % 2 == 0: set fill color to red else: set fill color to black draw square at (x, y) with size square_size

Double-check your modulo math. The condition (i + j) % 2 == 0 is necessary for the proper diagonal alternating pattern to emerge. The Fixed Code javascript The goal is to

If you are stuck on this exercise, you are likely encountering common hurdles like "index out of bounds" errors, incorrect color placement, or nested loop confusion. This comprehensive guide breaks down the logic, provides a working fix, and explains the core principles of 2D arrays. Understanding the Goal

If you are still experiencing issues, it might be due to a specific world configuration in your CodeHS session. Double-check that your fillRow logic correctly handles the odd/even row requirement, as that is the most common cause of failure.
