How to keep the array 'structure' inside a string in JavaScript [duplicate]

Question

my question is, if I have an array in javascript, let's say :

let x = [1, 2, 3, [4, 5, 6]]

And I want to transform it into a string that would look like this : y = "[1, 2, 3, [4, 5, 6]]", how should I do it? I tried this things:

let a = x.toString();
let b = y.toLocaleString();
let c = new String(x);

But the problem with it is that, all of them look like this:

"1, 2, 3, 4, 5, 6"

So, it completely removes the '[]'. How can I keep the array inside the string like this :

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

with the []

JSON.stringify(x) would yield "[1,2,3,[4,5,6]]". The other methods also don’t include spaces after commas. — Sebastian Simon

Does this helps?

 let y = [1, 2, 3, [4, 5, 6]];
 

 var x = JSON.stringify(y);
 
 console.log(typeof(x));
 
 console.log(JSON.stringify(y));
