删除对象数组中重复出现的元素，但保留一个属性更改的反应

function removeDuplicatesWithPropertyChangeReaction(objArray) {
  var newArray = [];

  objArray.forEach(function(obj) {
    var isDuplicate = newArray.some(function(newObj) {
      return obj.property === newObj.property;
    });

    if (!isDuplicate) {
      newArray.push(obj);
    } else {
      var existingObj = newArray.find(function(newObj) {
        return obj.property === newObj.property;
      });

      if (obj.reaction > existingObj.reaction) {
        existingObj.reaction = obj.reaction;
      }
    }
  });

  return newArray;
}

// 示例用法
var objects = [
  { property: 'A', reaction: 1 },
  { property: 'B', reaction: 2 },
  { property: 'A', reaction: 3 },
  { property: 'C', reaction: 4 }
];

var result = removeDuplicatesWithPropertyChangeReaction(objects);
console.log(result);

[
  { property: 'A', reaction: 3 },
  { property: 'B', reaction: 2 },
  { property: 'C', reaction: 4 }
]
