ArrowFx: Functional Programming for the masses

on YouTube ↗51m

" summary

ArrowFx claims to make FP practical in Kotlin by forcing side effects to the edge: code that contains effects fails to compile until wrapped in a FX block and each effect is wrapped with effect + bind (returns IO-like computations that run only at the entry point via runUnsafe). Concurrency via fibers and bracket supports fork/join, parallel race, guaranteed resource release, and cancellation. Demos print Hello World, spawn fibers and recover failures. Ecosystem pieces: Helios (JSON), Collect (dedupe/batching), streams; v0.9→0.91 changes and a 1.0 multi‑platform push are underway.
