I want to match field[123][33]["code"] where ["code"] is optional.

So I made this regex /field\[(\d*)\]\[(\d*)\]((?:\[")(.+)(?:"\]))?/g that is doing fine.

The problem is that it's coming in 4 groups 123, 33, ["code"] and code but I only want 3 groups 123, 33, code. Is it possible?

Here is a test example.

`field\[(\d*)\]\[(\d*)\](?:\["([^\][]+)"\])?`? In other words, `(?:())?` – Wiktor Stribiżew Feb 21 '19 at 12:51

you can simply add `?:` to the enclosing `()`: `field\[(\d*)\]\[(\d*)\](?:(?:\[")(.+)(?:"\]))?` – Kaddath Feb 21 '19 at 12:51
