Beyond Interfaces\n\nMost developers use TypeScript as a glorified linter. But its true power lies in its ability to model complex domain constraints through algebraic data types and conditional types.\n\n### Infer and Conditional Types\n\nUnderstanding infer within generic constraints unlocks the ability to unwrap return types, extract argument types from functions, and build complex mapping utilities.\n\n### Const Assertions\n\nas const is arguably the most underused feature in TypeScript. It allows you to create deeply immutable objects and tuple types from array literals, which is invaluable for defining configuration objects or status flags.
