Jindřich Ivánek On LinkedIn: F# Tips Weekly #5: Discriminated Union Types I am starting blog series "f# tips weekly", where i'll share f# programming tips i have learned along my f# journey. In f#, a sum type is called a “discriminated union” type. each component type (called a union case) must be tagged with a label (called a case identifier or tag) so that they can be told apart (“discriminated”).

F# – Serializing F# Record And Discriminated Union Types | Theburningmonk.com To create a discriminated union type in typescript, use the '|' operator to combine the set of types. here, the "discriminant" property can be used to distinguish between the different shapes of the object. Now that you have a full understanding of union types, let’s look at one of their special categories. creating discriminated unions is an extremely powerful way of composing types. To make the domain model self documenting i use f# discriminated union types. the model looks like that: | notstarted. | started of datetime. name: string. starttime: starttime. id: valueid. category: category. 11mo f# tips weekly #5: discriminated union types https://lnkd.in/e9rjfpaf #fsharp.

The solution for making the runtime "aware" of our compile time types is surprisingly simple. all we need is a tag for the types to be able to uniquely identify each variant, and discriminate based on that information. Among its many features, type guards and discriminated unions stand out as particularly useful for handling complex type scenarios. this tutorial will guide you through mastering these concepts, enhancing your typescript skills and allowing you to write more expressive and robust code.
