Is it possible to save multiple array of objects into one?

Question

I have multiple array of objects and I want to data1 to be stored to allData. Eventually data2 and data 3 will be appended to allData as well. I know this works for arrays. But does this works for an array of objects?

var allData;

var data1 = [
  {movie: 'Avengers Infinity War', rating: 4.8},
  {movie: 'Avengers End Game', rating: 4.5},
  {movie: 'Avengers End Age of Ultron', rating: 4.5}
]

var data2 = [
  {movie: 'Iron Man', rating: 4.3},
  {movie: 'Captain America: The First Avernger', rating: 4.7}
]

var data3 = [
  {movie: 'Thor', rating: 4.7},
]

allData = data1;
allData = allData.concat(data2);
allData = allData.concat(data3);
console.log(allData);

EDIT: I have updated my code to my question. My apologies.

How is an array of objects any different from a simpler array? Have you tried anything? — Anurag Srivastava

allData = [...data1, ...data2, ...data3]

or

allData = data1.concat(data2).concat(data3)

Add arrays to allData and use flat method.

var allData;

var data1 = [
  { movie: "Avengers Infinity War", rating: 4.8 },
  { movie: "Avengers End Game", rating: 4.5 },
  { movie: "Avengers End Age of Ultron", rating: 4.5 }
];

var data2 = [
  { movie: "Iron Man", rating: 4.3 },
  { movie: "Captain America: The First Avernger", rating: 4.7 }
];

var data3 = [{ movie: "Thor", rating: 4.7 }];

allData = [data1, data2, data3].flat();

console.log(allData);
