After mapping over an `Either<String, typeB>...

# arrow

After mapping over an Either<String, typeB>, I ended up with an Either<String, String>. Is there a simple way of returning the resulting String whichever is there, i.e. to convert the Either<String, String> to a String?

Or should a fold like this be used?:

return stringEither.fold({
    it
}, {
    it
})

yeah, probably the fold makes most sense

[tginiotis]

apparently calling .fold() without arguments achieves the result

[tginiotis]

or not

[pakoito]

seems okay to me 😄

[pakoito]

fold w/o parameters should not compile

[tginiotis]

.fold() without parameters does compile though

[tginiotis]

but when the value is a Left one it does not return it
