这两个对象可以通过遍历它们的属性来进行比较，可以使用 for...in 循环遍历对象的属性，并使用 hasOwnProperty() 方法来判断属性是否属于该对象，然后进行值的比较。可以使用对象的属性名来获取属性值，比较两个对象的属性值是否相同。如果属性值不同，则可以将其记录下来，以便于后续的处理。

例如，可以使用以下的代码来比较这两个对象的属性值是否有变化，并获取变化的值：

function compareObjects(obj1, obj2) {
  let changes = {}; // 用于记录变化的属性

  // 遍历obj1的属性
  for (let prop in obj1) {
    if (obj1.hasOwnProperty(prop)) {
      // 判断obj2是否存在该属性，并且值是否相同
      if (obj2.hasOwnProperty(prop) && obj1[prop] !== obj2[prop]) {
        changes[prop] = [obj1[prop], obj2[prop]]; // 记录变化的属性和值
      }
    }
  }

  // 遍历obj2的属性，查找新增的属性
  for (let prop in obj2) {
    if (obj2.hasOwnProperty(prop) && !obj1.hasOwnProperty(prop)) {
      changes[prop] = [undefined, obj2[prop]]; // 记录新增的属性和值
    }
  }

  return changes;
}

// 测试

上述代码中，compareObjects() 函数接收两个对象作为参数，返回一个记录属性变化的对象。该函数内部使用 for...in 循环遍历两个对象的属性，并使用 hasOwnProperty() 方法来判断属性是否属于该对象。如果属性值不相同，则将其记录到 changes 对象中，并返回 changes 对象。
