无法访问数组内 json 对象的属性

Question

I have an array of objects like

[
   {
      "id":17368,
      "creationDate":1566802693000,
      "status":"InProgress",
      "type":"NEW",
      "agentType":"Master"
   },
   {
      "id":17368,
      "creationDate":1566802693000,
      "status":"InProgress",
      "type":"NEW",
      "agentType":"Master"
   },
   {
      "id":17368,
      "creationDate":1566802693000,
      "status":"InProgress",
      "type":"NEW",
      "agentType":"Master"
   },
   {
      "id":17368,
      "creationDate":1566802693000,
      "status":"InProgress",
      "type":"NEW",
      "agentType":"Master"
   }
]

But when trying to access the object property 'id' using console.log(array[0].id) throws a "cannot read property id of undefined error"

However just logging the first object with console.log(array[0]) prints the object successfully.

{id: 17368, creationDate: 1566802693000, …}

Also printing the list of ids using array.map(x => console.log(x.id)) prints the list of ids successfully.

I am in a situation where i need to access the first few specifically. Where am i going wrong?

Answer 1

try this console.log(array[0] && array[0].id)

or you can use get from lodash-es like this:

 import { get } from 'lodash-es'

const id=get(array[0], 'id', '')
