For managed packages, instead of solely using minified JavaScript, you should include unminified versions of the JavaScript files alongside the minified ones in static resources. For example, if you have a minified file named `foo.min.js`, you should also include an unminified version named `foo.js`.
The unminified version is required for security reviews, as minified files cannot be effectively parsed by human auditors or static analysis tools like Checkmarx. While the unminified file doesn't need to be served to users, it must be available for review. If you have intellectual property concerns, you can provide the unminified source files separately.
