# Script.Challenge

TypeBox Script enables type-level programming in runtime environments. This page collects TypeBox solutions to problems from the community-run [Type Challenges](https://github.com/type-challenges/type-challenges) project. These solutions are used to track functional parity with TypeScript.



## Solutions

Solutions to [Type Challenges](https://github.com/type-challenges/type-challenges) implemented with TypeBox's scripting engine. These solutions can also be used as a reference for writing type-level programs in TypeBox.
