在Javascript中分解对象

let myObject = {
  "version": 1,
  "traceId": "123456789",
  "session": {},
  "trigger": {
    "service": "some_service_is_here",
    "action": "update",
    "resource": "transaction"
  },
  "changesets": [
    {
      "update": {
        "retryCount": 1
      },
      "conditions": {
        "equal": {
          "subscriptionId": "aaaaaaaaaaaa",
          "transactionId": "bbbbbbbbbbbb"
        }
      }
    },
    {
      "update": {
        "retryCount": 2
      },
      "conditions": {
        "equal": {
          "subscriptionId": "ccccccccccccc",
          "transactionId": "dddddddddddddd"
        }
      }
    }
  ]
}

我需要从那个对象中提取一些属性。到目前为止,它是用洛达斯。有更多的提取正在进行,但他们是相当相同的。与Lodash一起使用的几个示例:

const trigger = _.get(myObject, 'trigger', null);
const retryCount = _.get(myObject, 'changesets[0].update.retryCount', null);

到目前为止,我有:

const trigger = _.get(myObject, 'trigger', null);

becomes

const {trigger} = myObject;

const retryCount = _.get(myObject, 'changesets[0].update.retryCount', null);

变成

const {changesets: [{update:{retryCount:retryCount = null}}]} = myObject;

现在我有几个问题:

1. 这是提取这些值的正确做法吗?
