Answer 1

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)

Answer 2

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);

Answer 3

 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);

Answer 4

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
}))
