基于数组对象列表的Javascript对象分组

function groupObjectsByProperty(objects, property) {
  return objects.reduce(function(result, obj) {
    var key = obj[property];
    if (!result[key]) {
      result[key] = [];
    }
    result[key].push(obj);
    return result;
  }, {});
}

// 示例用法
var objects = [
  { name: 'Alice', age: 25, gender: 'female' },
  { name: 'Bob', age: 30, gender: 'male' },
  { name: 'Charlie', age: 35, gender: 'male' },
  { name: 'Diana', age: 28, gender: 'female' },
  { name: 'Eva', age: 32, gender: 'female' }
];

var groupedObjects = groupObjectsByProperty(objects, 'gender');
console.log(groupedObjects);

{
  female: [
    { name: 'Alice', age: 25, gender: 'female' },
    { name: 'Diana', age: 28, gender: 'female' },
    { name: 'Eva', age: 32, gender: 'female' }
  ],
  male: [
    { name: 'Bob', age: 30, gender: 'male' },
    { name: 'Charlie', age: 35, gender: 'male' }
  ]
}
