Using ArkType for TypeScript runtime validation

ArkType is a library designed to provide runtime validation for TypeScript interfaces and classes, addressing the lack of runtime type checking in TypeScript by validating data at runtime while leveraging compile-time type systems. ArkType functions closely with the TypeScript type system, utilizing a string parser to convert type definitions into state objects for evaluation, validation, and type inference, ensuring identical behavior at both compile-time and runtime. The library offers a rich syntax for defining types, supports TypeScript features like primitive types, unions, expressions, and operators, and facilitates complex validation scenarios, including cyclic and recursive types. ArkType's unique "isomorphic" parser and pre-computed discriminants for discriminated unions provide distinct advantages, enhancing performance and making it a potential tool for higher code quality. Released in February 2023, ArkType remains in its 1.0-alpha stage but has gained attention for its capabilities and potential improvements, such as a JIT compilation strategy for enhanced performance.
