Rxjs is fantastic. Some fool of an interviewer said he thought it was “weird” that I use rxjs instead of redux libs like ngrx…

[@MultiWarrr]

Then how on hell he would ngrx effects without rxjs

[@NuradinPridon]

It is "weird" that the interviewer doesn't know NgRx is literally RxJS with some boilerplate.

The official rxjs docs makes no send to me. At 1:55 - what the heck are those "--" and "-|" after the arrow operator? I suppose it has something to do with time between each emission and the end of the stream. But I can't imagine what exactly does it mean, because it's not a valid JS code, just a "diagram"

[@Nojo524]

It actually represents an inner observable, through time. The -| at the end is when the inner observable completes.
