使用javascript从数组中打印x个x对象

Question

使用javascript对对象数组进行排序或查询的最佳方法是什么？说我想只获得前两个对象，然后是接下来的两个，或者从第5个开始获得5个？

我应该看一下哪些功能？

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
