build: forbid using TypeScript enums using eslint
[TypeScript enums][1] are an unusual TypeScript feature, because it's
one of the only features that is "not a type-level extension of
JavaScript".
This means TypeScript generates custom code for enums, which can cause a
bunch of issues, especially as this custom code can be built differently
depending on which bundler you use, and because of this, many people
discourage the use of enums:
- [The Dangers of TypeScript Enums][2]
- [Tidy TypeScript: Prefer union types over enums][3]
- [TypeScript: Handbook - Enums # Objects vs Enums][4]
I've added an ESLint rule that forbids TypeScript enums, as in most
cases, it's better to use string literals instead, e.g. like
`type a = "a" | "b" | "c";`.
