Below is an array in which I have to group 3 values in each object

var xyz = {"name": ["hi","hello","when","test","then","that","now"]};

Output should be below array -

Do a search for chunk. (NB Lodash has a chunk function) – Gruff Bunny Jun 27 at 7:59

Hi please refer this https://plnkr.co/edit/3LBcBoM7UP6BZuOiorKe?p=preview. for refrence Split javascript array in chunks using underscore.js

using underscore you can do

JS

 var data = ["a1", "a2", "a3", "a4", "a5", "a6", "a7", "a8", "a9", "a10", "a11", "a12", "a13"];
var n = 3;
var lists = _.groupBy(data, function(element, index){
  return Math.floor(index/n);
});
lists = _.toArray(lists); //Added this to convert the returned object to an array.
console.log(lists);

or

Using the chain wrapper method you can combine the two statements as below:

var data = ["a1", "a2", "a3", "a4", "a5", "a6", "a7", "a8", "a9", "a10", "a11", "a12", "a13"];
var n = 3;
var lists = _.chain(data).groupBy(function(element, index){
  return Math.floor(index/n);
}).toArray()
.value();

Instead of cutting and pasting the answer to the other question it would be more relevant to change it so that it applied to the data structure in this question. – Gruff Bunny Jun 27 at 10:56
