FAQ
Kaunsa regex flavor use hota hai?
JavaScript (ECMAScript) regex — jo browsers aur Node.js me chalta hai. Python/PCRE se thoda alag hai (e.g. lookbehind support browser pe depend karta hai).
Common patterns kya hain?
Email: [\w.+-]+@[\w-]+\.[\w.]+ | 10-digit mobile: [6-9]\d{9} | PIN code: \d{6} | PAN: [A-Z]{5}\d{4}[A-Z] | Date: \d{2}/\d{2}/\d{4}
g flag kya karta hai?
Global — text me SAARE matches dhoondta hai. Bina g ke sirf pehla match milta hai. Zyada tar cases me g on rakho.
Capture groups kaise dekhte hain?
Pattern me () lagao — e.g. (\d{2})/(\d{2}) me do groups hain. Har match ke neeche groups ki values dikhti hain.
