javascript | Object grouping

Question

I have an object. It looks like below:

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


        

Answer 1

If you're using underscore.js in your application then you can simply do the following:

var groups = _.groupBy(data, 'group'); // data is your initial collection

Or if you prefer not to use any library then you can do it yourself:

var groups = { };
data.forEach(function(item){
   var list = groups[item.group];

   if(list){
       list.push(item);
   } else{
      groups[item.group] = [item];
   }
});
