常见问题
Quick answers.
›Which regex engine does this use?
The playground uses the native JavaScript RegExp engine built into your browser, which supports standard features like lookaheads and capture groups.
›Is my test data sent to a server?
No. All pattern matching and text processing happens locally on your device in real-time.
›What are the common regex flags?
Common flags include `g` for a global search across the whole string, `i` for case-insensitive matching, and `m` for multiline mode.
›Can I test complex patterns?
Yes. You can write your own custom patterns or select from over 100 curated examples including URL validation, date formats, and HTML tag matching.
