    How to convert an object of objects (initial form of object) into object of arrays of objects (target form of object)

    I am  interested in every way to do this, but I am particularly interested in exploring reduce method. Because I guess it is possible in this case? I know how to convert an array to an object using array.reduce () but not such a transformation as below. 

    So, I don't know how to convert an object with objects (initial form of object) to an object of arrays of objects (target form of object)


    So, how to change this one:

    Starting situation: (initial form of object)

    const beforeConversion = {
    0: {
    name: "Mario",
    game: {
    home: "Nintendo", 
    playground: "Mario Kart",
    },
    },
    1: {
    name: "Yoshi",
    game: {
    home: "Nintendo",
    playground: "Mario Kart",
    },
    },
    2: {
    name: "Aya Brea",
    game: {
    home: "Sony",
    playground: "Parasite Eve",
    },
    },
    3: {
    name: "Solid Snake",
    game: {
    home: "Sony",
    playground: "Metal Gear",
    },
    },


    into this one:

    Expected result: (target form of object)

    const afterConversion = {
    Nintendo: [
    {
    name: "Mario",
    game: {
    home: "Nintendo",
    playground: "Mario Kart",
    },
    },
    {
    name: "Yoshi",
    game: {
    home: "Nintendo",
    playground: "Mario Kart",
    },
    },
    ],
    Sony: [
    {
    name: "Aya Brea",
    game: {
    home: "Sony",
    playground: "Parasite Eve",
    },
    },
    {
    name: "Solid Snake",
    game: {
    home: "Sony",
    playground: "Metal Gear",
    },
    },
    ],
    };
