Coordinate Conversion

// (row, col) to note (1-indexed)
const coordToNote = (row: number, col: number): number =>
  (row - 1) * 8 + (col - 1);

// note to (row, col)
const noteToCoord = (note: number) => ({
  row: Math.floor(note / 8) + 1,
  col: (note % 8) + 1
} as const);

// (x, y) to note (0-indexed)
const xyToNote = (x: number, y: number): number => y * 8 + x;
