map always returns array type, and you can use both value and key in iterator:

_.map(obj, (value, name) => ({name, value}))


const obj = {
  "ID_PROC_GD": "1",
  "DT_INI": "2018-06-06",
  "CD_GD": "1",
  "DT_INI_GD": "2018-05-28",
}

const result = _.map(obj, (value, name) => ({
  name,
  value
}))

console.log(result)

You can use Object.entries() and array#map.

let data = { "ID_PROC_GD": "1", "DT_INI": "2018-06-06", "CD_GD": "1", "DT_INI_GD": "2018-05-28"},
    result = Object.entries(data).map(([name, value]) => ({name, value}));
console.log(result);

You can use map

let data = { "ID_PROC_GD": "1", "DT_INI": "2018-06-06", "CD_GD": "1", "DT_INI_GD": "2018-05-28"},
    result = _.map(data, (value, name) => ({name, value}));
console.log(result);

 let obj = {
  "ID_PROC_GD": "1",
  "DT_INI": "2018-06-06",
  "CD_GD": "1",
  "DT_INI_GD": "2018-05-28" 
}

function getNameValObj(ele) {
  return {name: ele, value:obj[ele]};
}
 
let objList = _.flatMap(Object.keys(obj), getNameValObj);

  • While this might answer the authors question, it lacks some explaining words and/or links to documentation. Raw code snippets are not very helpful without some phrases around them. You may also find [how to write a good answer](https://stackoverflow.com/help/how-to-answer) very helpful. Please edit your answer - [From Review](https://stackoverflow.com/review/low-quality-posts/21428867) – Nick Nov 16 '18 at 08:22
  • Sure your are right. The explanation to solution is, lowdash _.flatMap method flattens the array of values by running each element in collection thru iteratee and flattening the mapped results. Method return new flattened array as per the return value of the method passed to second argument. – Mukund Nov 17 '18 at 04:36

You can try this:

let obj={
  "ID_PROC_GD": "1",
  "DT_INI": "2018-06-06",
  "CD_GD": "1",
  "DT_INI_GD": "2018-05-28",
}
_.map(obj,(item,index)=>({
    ['name']:index,
    ['value']:item
}))
