I don't get it - what's laughable about the idea of someone who can write both the front-end and back-end of a web application?

I know people who do that in practice.

Yeah, I can do that too. And a LITTLE bit more.

So what do you mean? That anyone can do this? I don't really know anything about front-end web development, so I couldn't do full-stack, and it isn't the case that anyone could.

I still can't understand why you think it's such a hilarious question that you laugh out loud about it?

Eh, I would absolutely say "yes" to that, and qualify it by what that means for me:

- practical experience with embedded devices - popular databases - web frontend APIs and common frameworks - popular backed platforms - Dev OPs and other types of automation

A lot of developers specialize, and relatively few branch out from that. I use the term because I don't want to be stuck in a single role.

Exactly this. It’s fitting that the term “full stack developer” came from the same guy that made geek merit badges a thing.
