How to push all objects into another array using javascript Lodash

Question

I web API call and in the background, it's running more than one time. So I received the response commentRows as data which I mention.

I have to map those data into another array.

var arrPush =[ ]; 
var commentRows ={  
   '@odata.context':'https:indexes',
   value:[  
      {  
         "key":"176611",
         "status":true,
         "errorMessage":null,
         "statusCode":200
      },
      {  
         "key":"176100",
         "status":true,
         "errorMessage":null,
         "statusCode":200
      }
   ]
}; 

arrPush.push(commentRows.value);

It generates the array for as,

[  
   [  
      {  
         "key":"176611",
         "status":true,
         "errorMessage":null,
         "statusCode":200
      },
      {  
         "key":"176100",
         "status":true,
         "errorMessage":null,
         "statusCode":200
      }
   ]
]

Needed

   [  
      {  
         "key":"176611",
         "status":true,
         "errorMessage":null,
         "statusCode":200
      },
      {  
         "key":"176100",
         "status":true,
         "errorMessage":null,
         "statusCode":200
      }
   ]

but I don't want the first [] has to be appended Can I use any Lodash for achieving this

arrPush.push(commentRows.value[0]); Do not use lodash for this — CertainPerformance

it may be [{"key":"176611","status":true,"errorMessage":null,"statusCode":200},{"key":"176100","status":true,"errorMessage":null,"statusCode":207}] sometime — Mukesh S

Here is an solution which can handle multiple elements in value array:

use _.flatten:

var arrPush = [];
var commentRows = {  
       '@odata.context':'https:indexes',
       value:[  
          {  
             "key":"176611",
             "status":true,
             "errorMessage":null,
             "statusCode":200
          }
       ]
    };

arrPush.push(commentRows.value);
arrPush = _.flatten(arrPush);  // here you get it

var arrPush = [];
var commentRows = {  
  '@odata.context':'https:indexes',
  value:[  
    {  
       "key":"176611",
       "status":true,
       "errorMessage":null,
       "statusCode":200
    }
  ]
};

commentRows.value.forEach(x => arrPush.push(x))
console.log(arrPush);

Use a forEach loop and push them into arrPush

Just push like this arrPush.push(commentRows.value[0]);

You can use

arrPush = _.concat(arrPush, commentRows.value[0]).

Here arrayToCopy is the array to which you want to copy the data.
