JSON object containing nested arrays in JavaScript

Question

JSON object containing nested arrays in JavaScript

In my current setup, I am utilizing a nested array with the following organization:

arr[0]["id"] = "example0";
arr[0]["name"] = "name0";
arr[1]["id"] = "example1";
arr[1]["name"] = "name1";
arr[2]["id"] = "example2";
arr[2]["name"] = "name2";

My goal now is to extract a nested JSON Object from this array

arr{
 {
 id: example0,
 name: name00,
 },
{
 id: example1,
 name: name01,
 },
{
 id: example2,
 name: name02,
 }
}

I had initially attempted to achieve this with JSON.stringify(arr);, however, it proved to be unsuccessful. If anybody has a solution, please share as I would greatly appreciate it.

Thank you!

Answer №1

If you're working with an array structured like this, where each subarray's initial item represents the ID and the second item represents the name:

const array = [["example0", "name00"], ["example1", "name01"], ["example2", "name02"]]

The first step is to transform it into an array of objects.

const arrayOfObjects = array.map((el) => ({
  id: el[0],
  name: el[1]
}))

After that, you can use JSON.stringify(arrayOfObjects) to obtain the JSON formatted data.

To ensure a successful array creation:

dataArr = [
 {
 code: 'sample0',
 title: 'title00',
 },
{
 code: 'sample1',
 title: 'title01',
 },
{
 code: 'sample2',
 title: 'title02',
 }
];

console.log(JSON.stringify(dataArr));

It is important to note that the array is being stored in a variable. Additionally, square brackets [] are used for creating arrays instead of curly braces {}.
