What, praytell, is this supposed syntax? A curl invocation? Including a link to a CDN resource in an HTML <script> tag?
A URL on the web is not what anyone would call a framework, I'm sorry to say. Is www.google.com a framework? Google programmed the server serving the content at that URL, right? Or what, is it only special URLs that only programmers use? Is your operating system a "framework"? Someone programmed that too, right? How about your coffee maker? That's also something someone programmed.
It's funny how the wikipedia article on CDNs doesn't mention the word "framework" once, yet the article on a real framework like React mentions the word 8 times and links to other frameworks and lists of frameworks.
Maybe, just maybe, it has a more narrow definition than "someone programmed it so you don't have to".
