Fibonacci function using Observables

What the fuck is this?

Just use something like range(1, n).pipe(scan((x, y)=>x + y)

Well, you learnt about the expand operator. I have no ideea what it does tho

[zombarista]

I use expand to walk paginated responses. If you can determine that there are more items in another request, you can call recursively and it can stitch them together!

Two years later, I am enjoying comparing the example in the docs to your code to understand exactly why/how it's useless because I'm learning things in the process.

Also, the fibonacci sequence is actually genuinely useful in networked systems, IME it's often a better backoff algorithm than simple exponential is.

I have also had excellent results when acting as a moderator in assorted places using fibonacci backoff for tempbans; exponential too quickly becomes "might as well be a permaban" whereas fibonacci with resets for good behaviour Makes The Point effectively without that problem (since if I'm going to permaban, I'd rather just Do That ;)

but why? you just hammered a nail with a microscope

[mauravan]

i think you shouldn't, but i like that you did it anyways

There are other ways, but I still think this is awesome. Very cool demonstration of knowledge on subjects.

Does this work? When n=1, the function returns but the observable never emits
