Email validation in JavaScript is used to ensure that a user has entered a valid email address before submitting a form or performing other actions in a web application. This is typically done by using regular expressions (regex) to match the email address against a specific pattern. A common pattern used for email validation is to check that the email address contains a specific set of characters, such as letters, numbers, and certain special characters. Additionally, the email address should contain an '@' symbol and a valid domain name. By using email validation in JavaScript, you can prevent invalid or malformed email addresses from being submitted to your server, which can help protect your application from spam or other malicious behavior. Additionally, it can also improve the user experience by alerting the user to an error in their input before they submit the form. It is important to note that javascript validation should not be the only approach to validate an email address, as it can be bypassed by malicious actors, server side validation should also be implemented to validate the entered email address.
