Can someone please help me resolve below object in javascript? I would be so grateful for your help.

//Current Object:
Data: {
 Name: [‘A’, ‘B’, ‘C’, ‘D’],
 Id: [1, 2, 3, 4]
 }

//Expected output: 
Data: {
 {Name: ‘A’, Id: 1},
 {Name: ‘B’, Id: 2},
 {Name: ‘C’, Id: 3},
 {Name: ‘D’, Id: 4}
 }

I have tried mapping it with Object.keys() and map() function, but it didn't help much. I am a beginner at Javascript, looking for someone's help.

You can't create an object:

const Data = {
 { Name: 'A', Id: 1 },
 { Name: 'B', Id: 2 },
 { Name: 'C', Id: 3 },
 { Name: 'D', Id: 4 }
};

But instead of that you can make an array:

const Data = [
 { Name: 'A', Id: 1 },
 { Name: 'B', Id: 2 },
 { Name: 'C', Id: 3 },
 { Name: 'D', Id: 4 }
];

Example code:

const data = {
 name: ['A', 'B', 'C', 'D'],
 id: [1, 2, 3, 4]
}
const mappedData = data.name.map((element, index) => ({
 name: data.name[index],
 id: data.id[index]
}));

You can use helper function with destructuring arguments and .map() like this:

const obj = {
 Data: {
 Name: ['A', 'B', 'C', 'D'],
 Id: [1, 2, 3, 4]
 }
};
const obj2ArrOfObj = ({ Name, Id }) => Name.map((name, idx) => ({ Name: name, Id: Id[idx] }));
const mappedObj = {
 Data: obj2ArrOfObj(obj.Data)
};
console.log(mappedObj);
