Test, validate and match regular expressions
This regular expression performs comprehensive email validation based on RFC 5322 standards. It enforces length limits on the local part (up to 64 characters) and ensures the domain has a valid extension of at least two characters. The pattern supports standard alphanumeric characters, special symbols, and quoted strings, making it suitable for strict email validation in JavaScript applications.
