Replies for: I'll start. For years, whenever I needed to handle an error in an RxJS stream with a side effect, I would catch the error and then rethrow it usin...

Another RxJS one:

I often combine streams with forkJoin or combineLatest and want the output as an object with stream names as keys. Before, I did it like this:

combineLatest([firstStream$, secondStream$]).pipe(
  map(([first, second]) => ({first, second}))
)
// output: { first: 'some value', second: 'some other value' }

But, you can directly do:

combineLatest({ first: firstStream$, second: secondStream$ })
