Introduction

Either with variants Left and Right is a general purpose sum type with two cases.

The Either type is symmetric and treats its variants the same way, without preference. For representing success or error, use Result<T, E> instead.

import { Either } from '@sniptt/monads';

const getLabel = (uncertainDate: Either<Date, string>): string => {
  return uncertainDate.match({
    left: date => date.toLocaleDateString(),
    right: text => `<abbr title="${text}">an uncertain date</abbr>`,
  });
};
