To prevent cross-site scripting (XSS) attacks, it's crucial to implement a combination of input validation, output encoding, and security headers. These measures help ensure that malicious scripts cannot be executed in your web application.

Example Concept: Cross-site scripting (XSS) is a vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. To mitigate XSS, use output encoding to escape user input before rendering it in the browser. Implement security headers like Content-Security-Policy to restrict the sources from which scripts can be executed.

Additional Comment:

Always validate and sanitize user inputs on both client and server sides.
Use libraries or frameworks that automatically handle output encoding, such as React or Angular.
Set the Content-Security-Policy header to limit script execution to trusted sources.
