Regex Tester & Validator

This regular expression is designed to validate email addresses by checking for a local part, an '@' symbol, a domain name, and a top-level domain. The local part and domain allow alphanumeric characters, hyphens, underscores, dollar signs, and hash symbols. The top-level domain is expected to consist of 2 to 5 alphabetical characters. It is commonly used in form validations to ensure user input resembles a standard email format.
