// slice from pre-generated string
function make_board4(width, height) {
    const chars = ' #'.repeat(width / 2 + 1);
    const odd_row = chars.slice(0, width) + '\n';
    const even_row = chars.slice(1, width + 1) + '\n';

    let rows = [];
    for (let i = 0; i < height; i += 2)
        rows.push(odd_row, even_row);
    return rows.slice(0, height).join('');
}
