Show HN: Find the Fox

A little function to help ;)

    { dr: -1, dc: -1 },
    { dr: -1, dc: 1 }
  ];

  for (let r = 0; r < rows; r++) {
    for (let c = 0; c < cols; c++) {
      for (const { dr, dc } of directions) {
        let match = true;
        const positions = [];

        for (let k = 0; k < wordLength; k++) {
          const nr = r + k * dr;
          const nc = c + k * dc;

          if (nr < 0 || nr >= rows || nc < 0 || nc >= cols || grid[nr][nc].textContent !== word[k]) {
            match = false;
            break;
          }
          positions.push(grid[nr][nc]);
        }

        if (match) {
          positions.forEach(cell => cell.style.backgroundColor = 'pink');
          console.log(`Found the word '${word}' at positions:`);
