I have an array like this:-
[
    {"brand":"cadbury","category":"silk"},
    {"brand":"biba","category":"tops"},
    {"brand":"cadbury","category":"fruitnut"}
]
And I want to convert it to below format, tried many ways to do but not succedded:-
[
    {"brand":"cadbury","category":[{"name":"silk"},{"name":"fruitnut"}]},
    {"brand":"biba","category": [{"name":"tops"}] }
]
Basically after loop I want to combine all brands together.
