Convert Nested Json Object In Reactjs?

I've been playing with json objects & using ReactJS. One of the json object represented by variable 'res'. How do I convert 'res' into 'b'. I'm also getting my json object 're

Solution 1:

You could do something like the following:

const a = {
  menu_1: {
    id: "1",
    menuitem: [{
      value: "1",
      onclick: "1()",
    }, ],
  },
  menu_2: {
    id: "2",
    menuitem: [{
      value: "2",
      onclick: "2()",
    }, ],
  },
};

let b = Object.keys(a).reduce(
  (p, c) => {
    for (let item of a[c].menuitem) {
      p.popup.menuitem.push(item);
    }
    return p;
  }, {
    popup: {
      menuitem: []
    }
  }
);

console.log(b);

I'm assuming that object a might have more than one menuitem in the array.

Solution 2:

You can use reduce this way

const a = {
  "menu_1": {
    "id": "1",
    "menuitem": [{
      "value": "0",
      "onclick": "0()"
    }, {
      "value": "0",
      "onclick": "0()"
    }]
  },
  "menu_2": {
    "id": "2",
    "menuitem": [{
      "value": "2",
      "onclick": "2()"
    }]
  }
}

const res = Object.values(a).reduce((all, {
  menuitem
}) => {
  all.popup.menuitem = [...all.popup.menuitem, ...menuitem]

  return all
}, {
  popup: {
    menuitem: []
  }
})

console.log(res)
