'Either' is a construct that provides a way to handle computations that can result in two distinct outcomes, often used for error handling or state management. In programming, it typically represents a value that can be one of two types, often capturing the success or failure of an operation, where one type represents a valid result and the other represents an error or an exception. This mechanism allows for clear separation of different outcomes and helps manage state in a functional way, making code more robust and easier to maintain.
congrats on reading the definition of Either. now let's actually learn it.
