3rd party JS code used to be snippets you were expected to copy-paste into your own code, or whole files you were expected to save and then load with a <script> tag before your own code.

Now there are like 50 ways to import JS code, most of them don't work most places, a lot of the code itself won't work in a browser at all (node-only), and a great deal of it is a pain to get into a browser if you're not fully bought into Node and probably also serving the whole "app" from Node.

It's about as easy to write your own JS in a browser, now, but it's vastly harder to start using code from the overall JS ecosystem.
