Abstract: A method and system for dynamically optimizing a script library are described. A request for a script library is received from a set of client devices. An instrumented version of the script library is transmitted to at least one of the set of client devices. The instrumented version of the script library includes code for tracing execution of the script library. Responsive to execution of the instrumented version of the script library at each one of the at least one of client devices, script library usage feedback indicative of usage of the script library at these client devices is received. An optimized version of the script library, generated based on the script library usage feedback by removing portions of the script library that are unused by the subset of client devices, is transmitted to the client device instead of the script library in response to a second request.
