How do make a JSON from an array

Question

Array:

myArr = [[1, 2, 3], [4, 5, 6]]

Expected output:

newArr = "[[1, 2, 3], [4, 5, 6]]"

I have tried:

myArr.toString()
String(myArr)
myArr = `${myArr}`

What I got by doing the above methods:

'1,2,3,4,5,6'

I gather what you would like to achieve is more or less serialization. We could use JSON.stringify in JavaScript to serialize an Array.

const array = [[1, 2, 3], [4, 5, 6]];
const serializedArray = JSON.stringify(arr));

To deserialize the Array, JSON.parse could be used.

const originalArray = JSON.parse(serializedArray));

const myArr = [[1, 2, 3], [4, 5, 6]];
const myArrString = JSON.stringify(myArr);

console.log(`Here is my string: ${myArrString}`);
