JavaScript - Add values from array to nested object

Question

I want to create a final object structure, as shown below.

let finalArr = {
 "friends": 
 [
 {
 "name": 'Jake',
 "friendsList": [
 "Friend1",
 "Friend2",
 "Friend3"
 ]
 },
 ]
}

I start with this

let finalArr = {
 "friends": [
 ]
}

In a loop, I obtain data and store it into an Array, like this

[
 {
 name: 'Jake',
 friendsList: [
 'Friend1',
 'Friend2',
 'Friend3',
 ]
 },

How do I add the array I generate from the loop to the object, so that I can obtain the final structure that I want above? I tried Json.push but that doesn't seem to work, nor does a regular loop and plug, as that gives me out of bounds issues.

• mplungjan: There is no JSON here. It is a POJO and what is Json.push ?
• John: finalArr.friends.push(yourObject)
• Mohan Aravind: Oops, that was a mistake my bad. Meant finalArr.friends.push wasn't working, but its because I was doing something dumb

Answer 1

You can access an object using bracket.

So, use finalArr.friends.push instead of Json.push

finalArr.friends.push({
 name: 'Jake',
 friendsList: [
 'Friend1',
 'Friend2',
 'Friend3',
 ]
 })

• mplungjan: JSON is a STRING NOTATION format, you have an object
• John: @mplungjan the object can be serialized as JSON.
• LogiStack: @mplungjan Ah. Right. :)
• mplungjan: @john Yes but that is irrelevant to the issues here

Answer 2

simply you can push your object into friends array

let finalArr = {
 "friends": [
 ]
}
for(let i=0;i<3;i++){
finalArr.friends.push({
 name: 'Jake',
 friendsList: [
 'Friend1',
 'Friend2',
 'Friend3',
 ]
 })
}
