javascript - 使用 javascript 从数组中打印 x 个对象

Question

使用 JavaScript 对对象数组进行排序或查询的最佳方法是什么？假设我只想获取前两个对象，然后获取接下来的两个对象，或者从第 5 个对象开始获取 5 个对象？

我应该查看哪些函数？

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

剩下的根据切片 API 进行数学计算。
