Answer 1

You can do that easily with Underscore.js:

_.chain(myObject.Apps[0].groups).sortBy("author").groupBy("author").value();

Outputs a JSON object:

{
 "John":[{"id":"4","name":"test group 4","category":"clinical note","author":"John"}],
 "LKP":[{"id":"2","name":"test group 2","category":"clinical image","author":"LKP"}],
 "RRP":[{"id":"1","name":"test group 1","category":"clinical note","author":"RRP"},{"id":"3","name":"test group 3","category":"clinical document","author":"RRP"}]
}
