Is there a way to divide a JSON array into multiple arrays to use with DataTables?

My goal is to transform a JSON array like this:

[Alex, James, John]

Into separate JSON arrays for each element, like this:

[[Alex], [James], [John]]

This will allow me to smoothly insert the JSON payload into a datatable using Datatables.JS.

I have made some progress with this code snippet:

var data = json;
while (data.length) {
  console.log(data.splice(0, 1));
}
return data;

While this successfully splits the JSON into individual arrays, when I attempt to use the 'data' variable in Datatables.JS, it fails due to the format being:

[Alex]
[James]
[John]

To resolve this issue, I aim to combine them into the desired JSON payload structure mentioned earlier before inserting it into the datatable.

Answer №1

One effective solution for your scenario is to utilize the map method.

When dealing with JSON data like

data = "["Alex","James","John"]"
, you can easily parse it using
JSON.parse("["Alex","James","John"]")
. This will yield an array object: ['Alex', 'James', 'John']

let personArray = ['Alex', 'James', 'John'];
let resultantArray = personArray.map(name => [name]);
console.log(resultantArray);

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

Answer №2

If I were to tackle this problem, I might approach it like so:

const names = ["Alex", "James", "John"];
const slicedNames = names.slice(1);
const splicedName = names.splice(0, 1);

console.log([splicedName, slicedNames]);

It's important to note that this solution expects the JSON data to be already converted into a JavaScript array.
