-## Relationship with ts-results

-This package is a friendly fork of the excellent https://github.com/vultix/ts-results/
-created due to time constraints on our (Lune's) side – we needed a package
-available with some fixes.
-
-Notable changes compared to the original package:
-
-* Added ESM compatibility
-* `Option` gained extra methods: `mapOr()`, `mapOrElse()`, `or()`,
-  `orElse()`
-* `Result` also gained extra methods: `mapOr()`, `mapOrElse()`,
-  `expectErr()`, `or()`, `orElse()`
-* `Ok` and `Err` no longer have the `val` property – it's `Ok.value` and `Err.error` now
-* There is `Some.value` which replaced `Some.val`
-* Boolean flags were replaced with methods:
-  * `Option.some` -> `Option.isSome()`
-  * `Option.none` -> `Option.isNone()`
-  * `Result.ok` -> `Result.isOk()`
-  * `Result.err` -> `Result.isErr()`
-
-We'll try to get the changes merged into the upstream package so that this fork
-can become obsolete.
