Just One More Type Trick

bro just one more type helper bro just one more mapped type just one more intersection bro i promise just one last type trick and the dx will be great Matt Pocock @mattpocockuk · 2d "it's unreadable" "a maintenance nightmare" "please don't do this" Your complex types don't need to be complex to use. Let me show you 🧵 // BAD - incomprehensible unless you're // a TypeScript Wizard type Color = "primary" | "secondary" | (string & {}); // GOOD - reusable and beginner-friendly type Color = StringWithAutocompleteOptions< "primary" | "secondary" >;

A screenshot shows a humorous post by Matt Pocock about repeatedly adding increasingly complex TypeScript type helpers, mapped types, intersections, and autocomplete tricks. The joke is that the developer keeps promising one last type trick while turning a simple type into something difficult to read, then presents a supposedly beginner-friendly alternative. It is used as a reaction to overengineering, excessive type complexity, or endlessly tweaking code for developer experience.
