// but with default .match we get "eighthree" -> ['eight'] and for "sevenine" -> ['seven']

Ts quirk on “object”
https://github.com/typescript-eslint/typescript-eslint/issues/5947
Don't use `{}` as a type. `{}` actually means "any non-nullish value".
- If you want a type meaning "any object", you probably want `object` instead.
- If you want a type meaning "any value", you probably want `unknown` instead.
- If you want a type meaning "empty object", you probably want `Record<string, never>` instead.
