PROFILE
Toh Li Heng
Toh Li Heng enhanced the source-academy/modules and source-academy/js-slang repositories by building foundational type system infrastructure and configurable interpreter features. He introduced comprehensive TypeScript type definitions and module-level type awareness, refactored decorators, and improved import organization to strengthen code reliability and maintainability. In js-slang, he implemented typed module support and a language options system, including an any-type enforcement checker, all backed by expanded test coverage. Using JavaScript and TypeScript, Toh’s work focused on code organization, static analysis, and type safety, enabling safer module interoperability, smoother onboarding for contributors, and a more scalable, configurable codebase without addressing bug fixes.
