I can’t think of a single functional language that offers what effect gives you, though. A fully typed and declarative error channel, managed dependency layer with compile time safety, excellent resource management, the best parsing/validating/serializing library I’ve used in TypeScript, concurrency, streams, cache, otel primitives baked in…
In all fairness it does require buy-in and gradual adoption isn’t perfectly seamless or frictionless, but I think it’s worth it. They’ve done an outstanding job with it.
