What are discriminated unions? discriminated unions, also known as tagged unions or algebraic data types, are a powerful feature in typescript. they are used to model a variable that can hold multiple types of values but must conform to a specific set of rules defined by these types. a discriminated union is composed of multiple union members that share a common discriminant property. Using discriminated unions in your typescript code brings numerous benefits: improved type safety: with discriminated unions, typescript can ensure that all possible variants of a type are accounted for, eliminating the risk of undefined or unexpected behavior at runtime. Let’s say that we have the following discriminated union, classifying our detected features into either points or lines: the feature type is a discriminated union of point and line, so we could write some rendering code that looks like this:.
