الأسئلة الشائعة

Which regex flavor is this?

JavaScript (ECMAScript) - the same regex engine that runs in your browser and Node.js.

Does it support named groups?

Yes. Named capture groups like (?<year>\d{4}) are shown alongside numbered groups in the results panel.

Is my pattern or text uploaded?

No. Everything runs in your browser via the native RegExp engine.

Why is my pattern hanging?

You may have hit catastrophic backtracking - a common issue with nested quantifiers like (a+)+. Simplify the pattern.
