How to get two values from json object through lodash?

I am new in json and lodash. I want to get two values from Json. But right now i am getting only one value from return. So I want to get together both values.

[
{
"_id": {   
"mm": 2,   
"hr": 9,
"sl": 1
},
"tot": 188
},
{
"_id": {   
"mm": 2,   
"hr": 4,
"sl": 3
},
"tot": 622
},
{
"_id": {   
"mm": 2,   
"hr": 12,
"sl": 5
},
"tot": 484


 }]

_.map(resp.data,function(res){ return res._id.hr})

I want to also get sl value with "hr" Like 9:1, 4:3, 12:5. (hr:sl).

Hope this help:

var json = [
   {
      "_id":{
         "mm":2,
         "hr":9,
         "sl":1
      },
      "tot":188
   },
   {
      "_id":{
         "mm":2,
         "hr":4,
         "sl":3
      },
      "tot":622
   },
   {
      "_id":{
         "mm":2,
         "hr":12,
         "sl":5
      },
      "tot":484
   }
]

$data = _.map(json,function(res){ return (res._id.hr + ':' + res._id.sl)})
console.log($data);

Ok, if you want to put another ten minutes for the _.id.sl variables, you can do this:

$data = _.map(json,function(res){
$hour = res._id.hr;
$minute = (res._id.sl*10) + 10;
if ($minute >= 60)
{
    $minute = '00';
  $hour = $hour +1;
}
return ($hour + ':' + $minute)
})

Here's the fiddle: https://jsfiddle.net/dedenbangkit/qcqbsb69/1/

Sorry, I think you don't want 24 become 25 for hour format isn't it? so this will might better for you, assuming that 00:00 is middle night.

$data = _.map(json,function(res){
$hour = res._id.hr;
$minute = (res._id.sl*10) + 10;
    if ($minute > 50){
      $minute = '0' + (60 - $minute);
      $hour = $hour + 1;
    }else{
      $hour = $hour + 1;
    }

    if($hour > 24){
      $hour = '0' + (- 24 + $hour);
    }

    return ($hour + ':' + $minute)
})

You can return an object with all the data you want, for example:

var results =_.map(a, function(res) { 
  return { hr: res._id.hr, sl: res._id.sl }; 
});

Using Vanilla JS

var arr = [
{
"_id": {   
"mm": 2,   
"hr": 9,
"sl": 1
},
"tot": 188
},
{
"_id": {   
"mm": 2,   
"hr": 4,
"sl": 3
},
"tot": 622
},
{
"_id": {   
"mm": 2,   
"hr": 12,
"sl": 5
},
"tot": 484
 }]
 
 var res = arr.map((item) => item._id.hr + " : " + item._id.sl )
 console.log(res)

Using loaddash

var arr = [{
  "_id": {   
  "mm": 2,   
  "hr": 9,
  "sl": 1
  },
  "tot": 188
  },
  {
  "_id": {   
  "mm": 2,   
  "hr": 4,
  "sl": 3
  },
  "tot": 622
  },
  {
  "_id": {   
  "mm": 2,   
  "hr": 12,
  "sl": 5
  },
  "tot": 484
  }]
 
var res = _.map(arr, (item) => item._id.hr + " : " + item._id.sl )
 console.log(res);
