How wouldn’t it be reused? Besides, what will happen if you need to change a constant in the enum from „a“ to „b“? Compiler won’t help you to spot all the place

How wouldn’t it be reused? Besides, what will happen if you need to change a constant in the enum from „a“ to „b“? Compiler won’t help you to spot all the places like ˋˋˋif (value == „a“)ˋˋˋ, it will quietly become unreachable in runtime.
- teaearlgraycold 2y agoYou underestimate TypeScript. Your example will give a compiler error: This comparison appears to be unintentional because the types '"a"' and '"b"' have no overlap.(2367) https://www.typescriptlang.org/play/?#code/MYewdgzgLgBAZiEAuGAiAhqmBeNmDcAUIQJZwwAUCIO2uqARqgJQwDehMXMokIANgFMAdPxABzChgCeIFkQC+hIA https://www.typescriptlang.org/play/?#code/MYewdgzgLgBAZiEAu... It's features like these that make Python/Ruby/etc. type-checkers insufficient substitutes for TypeScript. I think my example wasn't the best. Of course "active" | "inactive" would get reused. But if it's just a little function flag it could easily be a one-off.
