"Using the push method in JavaScript allows for the combination of arrays rather than

Looking to retrieve data from an API and store it in an array. When I assign the value directly using '=', the desired data is displayed. However, when attempting to add elements using 'push', they are added as another array.

Below is the console log of the array after initial assignment this.elements = response.data

Proxy {0: {…}, 1: {…}, 2: {…}}
[[Handler]]: Object
[[Target]]: Array(3)
0: {ID: 40, created_at: "2021-03-13T22:15:09.769066+03:00", updated_at: "2021-03-13T22:15:09.769066+03:00", DeletedAt: null, user_id: 19, …}
1: {ID: 39, created_at: "2021-03-13T22:15:06.779473+03:00", updated_at: "2021-03-13T22:15:06.779473+03:00", DeletedAt: null, user_id: 19, …}
2: {ID: 38, created_at: "2021-03-13T22:15:01.738319+03:00", updated_at: "2021-03-13T22:15:01.738319+03:00", DeletedAt: null, user_id: 19, …}
length: 3
__proto__: Array(0)
[[IsRevoked]]: false

Now, upon using the push method to add elements

this.elements .push(response.data)

Proxy {0: {…}, 1: {…}, 2: {…}, 3: Array(3)}
[[Handler]]: Object
[[Target]]: Array(4)
0: {ID: 40, created_at: "2021-03-13T22:15:09.769066+03:00", updated_at: "2021-03-13T22:15:09.769066+03:00", DeletedAt: null, user_id: 19, …}
1: {ID: 39, created_at: "2021-03-13T22:15:06.779473+03:00", updated_at: "2021-03-13T22:15:06.779473+03:00", DeletedAt: null, user_id: 19, …}
2: {ID: 38, created_at: "2021-03-13T22:15:01.738319+03:00", updated_at: "2021-03-13T22:15:01.738319+03:00", DeletedAt: null, user_id: 19, …}

1: {ID: 33, created_at: "2021-03-13T10:59:06.521453+03:00", updated_at: "2021-03-13T10:59:06.521453+03:00", DeletedAt: null, user_id: 19, …}
2: {ID: 32, created_at: "2021-03-13T10:58:59.111903+03:00", updated_at: "2021-03-13T10:58:59.111903+03:00", DeletedAt: null, user_id: 19, …}

How can I add elements individually to the array instead of adding the whole array?

Answer №1

To add elements to an array using the spread operator, you can utilize the push method like this:

this.items.push(...newData)

For example:

const list1 = [5, 6, 7];
const list2 = [18, 19, 20];
list1.push(...list2);
console.log(list1);

Answer №2

An efficient way to combine the existing array with a new one is by utilizing the spread operator:

this.list = [...this.list, ...newData]
