JavaScript Libraries Are Almost Never Updated Once Installed

This post contributes to the website content optimization thread by analyzing data from CDNJS to reveal a significant trend: JavaScript libraries are rarely updated once installed on websites. This has implications for the long-term health and maintainability of the web, as older versions persist indefinitely. The analysis of jQuery and TweenMax versions demonstrates that new releases do not significantly displace older ones, and even very old versions continue to receive substantial traffic. This highlights a challenge for the web platform in supporting aged conventions and suggests a need for better mechanisms to encourage library updates.
