flatten nested object using lodash

Question

flatten, flattenDeep or flattenDepth of lodash only accept array. How to flatten nested object?

var data = {
  "dates": {
    "expiry_date": "30 sep 2018",
    "available": "30 sep 2017",
    "min_contract_period": [{
      "id": 1,
      "name": "1 month",
      "value": false
    }, {
      "id": 2,
      "name": "2 months",
      "value": true
    }, {
      "id": 3,
      "name": "3 months",
      "value": false
    }]
  },
  "price": {
    "curreny": "RM",
    "min": 1500,
    "max": 2000
  }
}

I want nested property to be the first level, like expiry_date should be level 1, not within dates, and I think dates should be gone, it's not needed anymore. I can do it manually, use map() but I'm looking to use lodash to ease the task.

Answer 1

One of the easiest solutions would be, merging the nested object with parent,

_.merge(data, data.dates);

This will bring all data.dates property into data. Then delete data.dates

delete data.dates
