Using a CDN: Using a CDN helps bring resources closer to the user by
caching them in multiple locations around the world. Once those
resources are cached, a user’s request only needs to travel to the

to the origin server each time.

You can modify and fix certain issues in a library that create

will have to use the original library's code instead thus losing these
fixes.
