Sites like Hexbear source scripts from only one domain (hexbear.net). I like those sites.
Other sites loop in a few JavaScript libraries. They have a few domains asking for permissions. That's okay. A little lazy, but acceptable.
Then you have the corporate websites with, like, sixty JavaScript domains. Holy crap! What are scripts from facebook, pinterest, and amazon doing on this news article about jellyfish? 
And the website is perfectly functional with just a couple domains enabled. 
Node is one of those things that baffles me. Why use a shitty language originated during a two-week cocaine binge by Brendan Eich as the basis of server backends? I can understand the tragic compatibility need to keep using Javascript in browsers, especially after Google inexplicably pulled the plug on Dart as a potential browser language and redesigned it to be just another Typescript clone that's been crippled so that it can transpile to Javascript. But it's not like we're starved for good backend languages.
I think it was out of a desire to reduce staff tbh. Around the time the concept of a full stack dev was becoming popular and the idea is one person does everything rather than splitting the various components into different specialties and since js was mandatory on the browser why not get the frontend devs to write the backend as well. It was a tech bro psyop thats my theory.
What sort of incompetent no-long-term-planning 3-second-attention-span halfwit would ever think that using a dynamically-typed scripting language with barely any standard library and which is famous for undefined behaviour would make a good backend language, just to save a few dollars in the short term, was ever a good idea?
Oh, right, just every tech company upper-management drone on the planet.
It's a fun programming language.
