    Variants and Pattern Matching Variants using switch in Reason

    Variants are known as tagged unions in Computer Science. They allow us to express multiple options that are exclusive, as a data structure. A concept that isn't available in too many programming languages and yet such a powerful concept.

    We explore how to create variants and constructors in ReasonML and briefly touch on how to pattern match them to extract data.
