The terminology of signals (and slots) has been used in Qt [0] since the 1990s I believe.

Still, it is unfortunate that the article begins with “Let's start with an extremely broad definition” (of signals), then continues with what sounds like signals in general, mentioning React only as an example, but then turns out wanting to only talk about signals in the particular reactive UI sense common in web development, without properly introducing that narrowing of focus.

I guess that focus can be expected from a blog on a site about a TypeScript signals library, but from the way the first few paragraphs are written, it’s certainly confusing when reading the article without further context, coming from HN.

Was confusing then and is still confusing now.
