From my reading I understood that Qt signals & slots (and Qt events) are much more closely related to JavaScript events (native and custom).

In both you can explicitly emit, handle, listen to events/signals. JavaScript events seem to combine both Qt signals & slots and Qt events. Of course without the type safety.

For example, taken from https://doc.qt.io/qt-6/signalsandslots.html

"Signals are emitted by objects when they change their state in a way that may be interesting to other objects."

However what I think they are proposing in the article is a much more complex abstraction: they want to automate it so that whenever any part of a complex graph of states changes, every piece of code depending on that specific state gets notified, without the programmer explicitly writing code to notify other pieces of code, or doing connect() or addEventListener() etc.

What are your thoughts on that? I'd be interested to hear since I'm sure you have more experience than me.
