What is Either in Scala? What are Left and Right in Scala? Explain Either/Left/Right Design Pattern in Scala?



What is Either in Scala? What are Left and Right in Scala? Explain Either/Left/Right Design Pattern ..

Answer / Ravit Kumar

"Either is a type in Scala that represents one of two possible values, either a value of type A or a value of type B. It's used to handle situations where a computation can result in one of two outcomes, but should be treated as a single unit.nnLeft and Right are the two cases of Either. Left carries an error value, while Right carries the successful result. For example, if you have a function that takes an integer and returns an Option[Int], you might use Either to represent the fact that the integer could either be present (Right(value)) or absent (Left(Error))."
