I'm pumped about the enum JS proposal, (that makes enums part of core JS, not just TS) -- not so much because of the proposal itself, but because one of the possible future directions for it would finally let JS evolve to crab. 🦀

A slide, titled "Algebraic Data Type Enums": - Algebraic Data Type (ADT) enums are structured objects with some form of discriminant property. - ADT enums would tie in nicely with Extractors and Pattern Matching A code sample follows: enum Option { Some(value), None() } enum Result { Ok(value), Error(reason) } match (opt) { Option.Some(let value): console.log(value); Option.None(): console.log("<!-- raw HTML omitted -->"); }
