Common Regex Patterns Explained

Email Validation

Matches standard email formats. Not RFC-compliant (that's much more complex), but covers 99% of real-world cases.

URL Matching

Matches http/https URLs. Captures protocol, domain, and path. Great for extracting links from text.

Password Strength

Checks for minimum 8 characters, uppercase, lowercase, number, and special character.

Hex Colors

Matches 3-digit and 6-digit hex color codes like #fff or #6366f1. Useful for parsing CSS.
