How to group JSON data in JavaScript?
To group JSON data, you need to extract all the keys and use the push(). Following is the code −
Example
var details= { "1": { name:"John" }, "2": { name:"John" }, "3": { name:"David" } var objectWithGroupByName = {}; for (var key in details){ var name = details[key].name; if (!objectWithGroupByName[name]){ objectWithGroupByName[name] = []; } objectWithGroupByName[name].push(details[key]); } console.log(objectWithGroupByName);
To run the above program, you need to use the following command −
node fileName.js.
Output
Here, my file name is demo122.js. This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo122.js { John: [ { name: 'John' }, { name: 'John' } ], David: [ { name: 'David' } ] }
