ArkType 2.2: Use Your TypeScript Types as Runtime Validators

A new TypeScript-first validation library is streamlining the way developers handle data validation by unifying types and validators. With this tool, you define a type once, and it serves as both the static type and the runtime validator, reducing duplication and potential errors in your codebase.

The latest v2.2 release introduces type.fn, a feature that brings runtime-validated functions to the library. This enhancement allows developers to automatically check both function inputs and return values at runtime, ensuring greater reliability and type safety throughout their applications.

With its innovative approach and focus on developer productivity, this library is quickly becoming a valuable asset for TypeScript projects that demand robust, type-safe validation.
