İpuçları ve En İyi Uygulamalar
- The "email" regex is the canonical compromise: short, fast, catches typos. For full RFC 5322 compliance use the multi-thousand-character version (you almost never need it).
- For password strength, the included pattern is a "minimum acceptable" check — use the password-strength-checker tool for nuanced scoring.
- Regex is great for validation, terrible for parsing. Use a dedicated parser for HTML, JSON, dates with timezones, etc.
- JavaScript regex doesn't support recursive patterns — for nested-bracket matching, use a real parser.
- For multi-line input, set the `m` flag so `^` / `$` match line starts/ends, and the `s` flag to make `.` match newlines.
