Well, it was my obvservation reading typescript code (never wrote a line in this language) with a background from java and then c# and then scala. The observables part felt really easy even without knowing the language syntax, but I suppose that the past 4 years of scala made me instantly translate the code in functional fashion and it was all smooth. On the other, while it's wrapped differently, the whole idea of "this object will start emitting events, and we will be having functions as callback on them defined in various objects" really feels a lot like good old java observables/listeners, even if it's applied with a different paradigm. The stream part really feels like an implementation detail to me, it's just less boilerplate than before. Then again, it was just an anecdote based on reading code in a language I don't use ^^ javascript and typescript aren't even mentioned on my resume, for good reasons, so I should be safe in interviews !
