When you run the code, you should see:
, which determines if a row or column index is even or odd. A standard checkerboard pattern follows these rules: Even rows (0, 2, 4, 6) : Start with [0, 1, 0, 1, 0, 1, 0, 1] Odd rows (1, 3, 5, 7) : Start with [1, 0, 1, 0, 1, 0, 1, 0] Step-by-Step Implementation Initialize the Grid Create an empty list (often named ) to hold the rows of your checkerboard. Outer Loop for Rows loop to iterate through the 8 rows of the board. Alternating Row Logic Within the outer loop, check if the current row index is even or odd: i % 2 == 0 : Append a row where elements alternate starting with : Append a row where elements alternate starting with Nested Loop Method (Alternative) // Create the canvas var canvas = document
The most efficient way to solve this is to first create a blank board and then use a nested loop to "draw" the pattern. Outer Loop for Rows loop to iterate through
