We match the provided target strings exactly by escaping all regex special characters that appear in the literals. Our regex uses a non-capturing group with alternation (|) for each target item, and we anchor the pattern with ^ and $ to ensure we match the entire string exactly. Each target is handled by escaping characters such as ., +, ?, /, (, ), {, }, ", etc., where needed. For example, for the email 'user.name+tag@example.com' we use 'user\.name\+tag@example\.com'. This ensures only and exactly the provided strings are matched. Below is the JavaScript regex as a simple string (without the surrounding slashes and flags).
