可以使用reduce函数进行分组。其中，使用组合字符串作为分组的key。

示例代码如下：

const arr = [ { name: 'Alice', age: 30, gender: 'female' }, { name: 'Bob', age: 25, gender: 'male' }, { name: 'Charlie', age: 35, gender: 'male'}, { name: 'David', age: 30, gender: 'male'}, { name: 'Eve', age: 25, gender: 'female'}, { name: 'Frank', age: 35, gender: 'male'}, ];

const groupBy = (array, property1, property2) => { return array.reduce((acc, obj) => { const key = obj[property1] + '-' + obj[property2]; if (!acc[key]) { acc[key] = []; } acc[key].push(obj); return acc; }, {}); };

const groups = groupBy(arr, 'gender', 'age');

console.log(groups); // Output: // { // "female-30": [{name: "Alice", age: 30, gender: "female"}], // "male-25": [{name: "Bob", age: 25, gender: "male"}, {name: "David", age: 30, gender: "male"}], // "male-35": [{name: "Charlie", age: 35, gender: "male"}, {name: "Frank", age: 35, gender: "male"}], // "female-25": [{name: "Eve", age: 25, gender: "female"}] // }
