使用heron公式计算周长和面积的javascript函数

function calculateTriangleMeasurements(a, b, c) {
  // 计算周长
  const perimeter = a + b + c;

  // 使用Heron公式计算面积
  const semiPerimeter = perimeter / 2;
  const area = Math.sqrt(
    semiPerimeter *
      (semiPerimeter - a) *
      (semiPerimeter - b) *
      (semiPerimeter - c)
  );

  return {
    perimeter: perimeter,
    area: area,
  };
}

// 示例调用
const triangle = calculateTriangleMeasurements(3, 4, 5);
console.log("周长：" + triangle.perimeter);
console.log("面积：" + triangle.area);
