I have a regex to add thousand separators and I get a Denial of Service security hotspot in sonarcloud.

I have this code

function thousandSeparator(value: number | string | null | undefined) { return value?.toString().replace(/B(?=(d{3})+(?!d))/g, "u00a0"); }

and this is the explaination of the security hotspot

Make sure the regex used here, which is vulnerable to super-linear runtime due to backtracking, cannot lead to denial of service.

How can I fix this?
