In 2013 we wrote async javascript & the only patterns we had were races and callbacks & we liked it. Now we got 100*+ abstractions over races and callbacks.
* most of those are #rxjs
#Rxjs
#rxjs created an industry, a massive enterprise in wondering if observables need to be unsubscribed. I think the anti-unsubscription crowd is right in the sense of
- We don't know what is happening in unsubscribe(), maybe nothing
- The computer will be shut down, we will all die, and the universe will be cold and black and so should we really care about collecting the garbage early
- Out-of-memory will force garbage collection organically as the user reboots.
#dotnet has the same thing going on for IDisposable, with objects implementing IDisposable but not actually doing anything in IDisposable. (And if you didn't call IDisposable, the DB server would crash, which I guess is a natural way to handle closing all those handing connections without writing boilerplate code)
