Welcome to my tutorial on email address validation using regular expressions. Email validation is crucial in web development to ensure that user input conforms to the correct email format, preventing security vulnerabilities and data integrity issues.
In this tutorial, I'll be discussing a regular expression for validating email addresses. The regex pattern checks for the presence of necessary components like the username, domain, and top-level domain, while ensuring the correct structure of the email address. I'll explain each component of the regex pattern and provide examples to illustrate how it works. Here's the code snippet of the regex:
/^([a-z0-9_.-]+)@([\da-z.-]+).([a-z.]{2,6})$/
