Transform an array into a string while keeping the [ ] inside the string [duplicate]

Question

I have an array of integers

element= [12,456]

I would like to transform this into

desired_output = "[12,456]"

I tried toString but it fails. For example element.toString() outputs "12,456" which is not what I want.

It's tricky, I want to keep the [ and the ] inside the string.

@SudhirBastakoti please put a formal answer so I can give you points:) thanks it worked — Mathieu

by the way is it possible to go the other way around like move from "[12,456]" to [12,456] ? — Mathieu

@mplungjan I tried but it seems I did not know json was the key, once you sue this keyword the answer abound! I was instead getting strange splits and joins and none working. — Mathieu

This might work:

JSON.stringify(YourArray);

a = [1, 2, 3]
desired = `[${a.join(',')}]`
console.log(desired) //"[1,2,3]"
