Welcome to the future with 50y old technology. There is an obscure emacs extension, swank js, that runs a nodejs daemon that speaks slime to emacs.
It allows you to work with js the same way you'd work with lisp, evaling lines or buffers into a live nodejs instance.
I use it (in combination with org-babel) to talk to live instances of remote services, to inspect data, experiment, but also as kind of an on-the-fly UI
It allows you to inject js into a browser as well, handy for js dev or even on the fly data scraping/web manipulation. Super useful yet not very well known.
I feel like people aren't freaking out enough about how awesome it is that big universities are publishing their lectures online, some of my favorite ones are
I turned these into podcasts that you can download here
about behavioral biology letures, in order to fall in love with Sapolsky, check his short talk on toxoplasmosis parasite
Also, I think his lecture on biological underpinnings of religiosity that is a part of this course is not in the playlist, I think because its pretty controversial, you can find it as an old recording here
will add more stuff to this folder with time.
