javascript | Object grouping

Question

I have an object. It looks like below:

[
  {
    \"name\":\"Display\",
    \"group\":\"Technical detals\",
    \"id\":\"60\",
    \"value\":\"4\"
  },
  {
           


        

Answer 1

Try

let g = (d,h={},r={},i=0)=>(d.map(x=>(y=x.group,h[y]?1:(h[y]=++i,r[h[y]-1]=[]),r[h[y]-1].push(x))),r);
console.log( g(data) );

let data=[
  {
    "name":"Display",
    "group":"Technical detals",
    "id":"60",
    "value":"4"
  },
  {
    "name":"Manufacturer",
    "group":"Manufacturer",
    "id":"58",
    "value":"Apple"
  },
  {
    "name":"OS",
    "group":"Technical detals",
    "id":"37",
    "value":"Apple iOS"
  }
];


let g = (d,h={},r={},i=0)=>(d.map(x=>(y=x.group,h[y]?1:(h[y]=++i,r[h[y]-1]=[]),r[h[y]-1].push(x))),r);

console.log(g(data));
