Frequently Asked Questions (FAQ)
Q: What is a global (g) search flag?
A: The global flag tells the regex engine to find all matches in the text, rather than stopping after the first match.
Q: What does case-insensitive (i) do?
A: The ignore-case flag ignores capital letters, matching both uppercase and lowercase characters (e.g. `[a-z]` matches both `a` and `A`).
Q: Are my test texts uploaded to a server?
A: No. All regex processing occurs locally in your browser memory, ensuring privacy.
Q: How do I match a literal dot (.) in regex?
A: Escape special characters like dots with a backslash (e.g., `\.` matches a literal period character, while `.` matches any character).
