Also effect-ts in TypeScript world, which is by far the most popular effect system around (quite sure it has overtaken Scala's ZIO from which it is inspired).

The ecosystem is massive.

Cons: TypeScript is a great type system but requires some investment to get the best out of it, it's also very verbose.

Pros: you have access to the entirety of the TypeScript ecosystem.
