When it was first introduced in 2006, jQuery became a fundamental tool for web developers almost immediately. It simplified JavaScript programming, making it easier to manipulate HTML documents, handle events, perform animations, and much more. Since then, it has played and continues to play a major role in the evolution of web standards and browser capabilities.

These improvements may include stricter input validation, improved handling of user-generated content, and better protection against XSS attacks. By upgrading, you adopt these best practices and strengthen the security posture of your application. Compliance Requirements : Many industries and regulatory frameworks require organizations to maintain up-to-date software and address known security vulnerabilities promptly.
