提取每个x和y的多个数组的最小值和最大值

// 定义包含多个数组的对象
const data = {
  array1: [{x: 1, y: 5}, {x: 2, y: 10}, {x: 3, y: 8}],
  array2: [{x: 4, y: 3}, {x: 5, y: 6}, {x: 6, y: 12}],
  array3: [{x: 7, y: 9}, {x: 8, y: 4}, {x: 9, y: 7}]
};

// 保存最小值和最大值的数组
const minMaxValues = [];

// 遍历每个数组，找到最小值和最大值
for (const key in data) {
  const array = data[key];
  let minX = Number.MAX_VALUE;
  let minY = Number.MAX_VALUE;
  let maxX = Number.MIN_VALUE;
  let maxY = Number.MIN_VALUE;

  for (const item of array) {
    minX = Math.min(minX, item.x);
    minY = Math.min(minY, item.y);
    maxX = Math.max(maxX, item.x);
    maxY = Math.max(maxY, item.y);
  }

  minMaxValues.push({minX, minY, maxX, maxY});
}

// 输出最小值和最大值
console.log(minMaxValues);
