Sorry if this has been asked before, but I couldn't find a good example of what I'm trying to accomplish. Maybe I'm just not searching for the right thing. Please correct me if there's an explanation of this somewhere. Anyway...

I have JSON data structured like so...

{Result:[

    {Level:ML,TeamName:Team 1,League:League 1},

    {Level:ML,TeamName:Team 2,League:League 2},

    {Level:ML,TeamName:Team 3,League:League 3},

    {Level:3A,TeamName:Team 4,League:League 1},

    {Level:3A,TeamName:Team 5,League:League 2},

    {Level:3A,TeamName:Team 6,League:League 3},

    {Level:2A,TeamName:Team 7,League:League 1},

    {Level:2A,TeamName:Team 8,League:League 2},

    {Level:2A,TeamName:Team 9,League:League 3},

]}

I would like to group, or restructure it like so...

{Result:[

    {ML:[

        {TeamName:Team 1,League:League 1},

        {TeamName:Team 2,League:League 2},

        {TeamName:Team 3,League:League 3}

    ]},

    {3A:[

        {TeamName:Team 4,League:League 1},

        {TeamName:Team 5,League:League 2},

        {TeamName:Team 6,League:League 3}

    ]},

    {2A:[

        {TeamName:Team 7,League:League 1},

        {TeamName:Team 8,League:League 2},

        {TeamName:Team 9,League:League 3}

    ]}

]}

How would I accomplish this with Javascript/jQuery? Unfortunately I can't edit what the server is sending me.

Just keep track of it all in an object:

let groups = Object.create(null);



data.forEach(item => {

    if (!groups[item.Level]) {

        groups[item.Level] = [];

    }



    groups[item.Level].push({

        TeamName: item.TeamName,

        League: item.League

    });

});



let result =

    Object.entries(groups)

        .map(([k, v]) => ({[k]: v}));
