Regex Tester & Validator

This JavaScript regex attempts to simulate a negative lookbehind using a negated character class, likely to prevent matching text if preceded by specific punctuation like `?:` or `):`. Literally, the pattern matches a single character that is not a question mark, colon, closing parenthesis, period, curly brace, zero, or comma. Following this initial boundary check, `(.+)` greedily captures all remaining characters on the line into Group 1. It is executed globally and case-insensitively, making it useful for targeted text extraction where certain prefixes must be avoided.
