使用javascript从数组中打印出x个对象中的x个

Question

用javascript排序或查询对象数组的最佳方法是什么？ 说我想只获取前两个对象，然后获取下两个对象，还是从第5个对象开始获取5个对象？

我应该看什么功能？

 var obj = [ { "_id": "58f8ffe7ce2bbf01c6164801", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164802", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164803", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164804", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164805", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164806", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164807", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164808", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164809", "isActive": true }, { "_id": "58f8ffe7ce2bbf01c6164810", "isActive": true } ] 

Answer 1

obj.slice(0,2);//first two
obj.slice(2,4);//next two

其余部分则基于切片API进行数学计算。
