By following these recommendations, you can be reasonably sure your code is free of XSS. Instead of scrutinizing code for exploitable vulnerabilities, the recommendations in this cheat sheet pave a safe road for developers that mitigate the possibility of XSS in your code. It contains code patterns of potential XSS in an application. This is a cross-site scripting (XSS) prevention cheat sheet by Semgrep, Inc.
