Es6: Create an array of objects from a json

I have a json in the below format.

 [
 "id": 1, 
 "name": "peter" ,
 "id": 2, 
 "name": "john" ,
 "id": 3, 
 "name": "justin" 
 .
 .
 "id": 500, 
"name": "david" ,
 ]

I am trying to create an array in batches of 10 in the below format

[

 "id": 1, 
 "name": "peter" ,
.
.
 "id": 10, 
 "name": "nixon" ,
,


 "id": 11, 
 "name": "nancy" ,
.
.
 "id": 20, 
 "name": "underwood" ,

.
.
]

I tried using reduce and tried for loop to loop through it, but was unsuccessful

Objects should have key value pairs. You cannot put another object inside without a key.

Here's a demo.

const str = "abcdefghigklmnopqrstuvwxyz";
let data = ;
for(let i = 0; i < 26; i++)
 data.push(id : i, name: str.charAt(i));


let res = data.reduce((acc, d) => 
 let groupId = Math.floor(d.id / 10);
 acc[groupId] = acc[groupId] , );
console.log(Object.values(res));

If you can ensure that id is the same sequence as their position in array, i think simply slice will better.
