grid of squares where the colors alternate between black and red (or other assigned colors), resembling a standard checkerboard. Key Technical Requirements:
You need an outer loop for rows and an inner loop for columns. 916 checkerboard v1 codehs fixed
If you are working through the CodeHS curriculum, you’ve likely encountered the assignment. It’s a classic challenge that tests your ability to use nested loops, coordinate systems, and conditional logic. grid of squares where the colors alternate between

Make sure your setPosition uses col * SQUARE_SIZE for the X-coordinate and row * SQUARE_SIZE for the Y-coordinate. Swapping these can sometimes cause the grid to render incorrectly if your canvas isn't a perfect square. 3. Infinite Loops
The most common mistake in "v1" is only checking if the column is even or odd. If you do that, every row will look identical, resulting in vertical stripes rather than a checkerboard. Use the sum of the row and column indices. If (row + col) is even , color it Red. If (row + col) is odd , color it Black. The Corrected Code (JavaScript/Karel Style)
