如何编写转置矩阵的方法？

function transposeMatrix(matrix) {
  const rows = matrix.length;
  const cols = matrix[0].length;

  // 创建新的矩阵
  const transposedMatrix = new Array(cols);
  for (let i = 0; i < cols; i++) {
    transposedMatrix[i] = new Array(rows);
  }

  // 转置矩阵
  for (let i = 0; i < rows; i++) {
    for (let j = 0; j < cols; j++) {
      transposedMatrix[j][i] = matrix[i][j];
    }
  }

  return transposedMatrix;
}

// 示例用法
const matrix = [[1, 2, 3], [4, 5, 6]];
const transposed = transposeMatrix(matrix);
console.log(transposed);
