Validation Libraries

Validation libraries are tools used in software development to ensure that data meets specific rules before processing. They check if the information inputted—like email addresses, phone numbers, or passwords—follows the required format and standards. For example, a library can verify if an email address contains an "@" symbol. By using these libraries, developers can improve the accuracy and security of their applications, reduce errors, and enhance user experience, making sure that only correct and valid data is used in their programs.
