Where do I look for a new-to-the-network technical-overview introduction to what a script/app/etc. basically is, including differences between them?
Basically, I'm looking for onboarding documentation pointers, or search terms to find that sort of info regarding all the (not legacy-deprecated-unavailable-etc.) sorts of functions discussed on StackApps, scripts, apps, or whatever. Terminology definitions and tutorials or well-documented examples... whatever I can read. Public stacks are my focus for now.
Also if other stacks, or unofficial / off-network resources deal with similar topics, pointers greatly appreciated.
