Worked on the nodejs/amaro repository to deliver loader support for JavaScript files, introducing an experimental strip types flag to extend asset processing beyond TypeScript. Focused on enhancing compatibility for mixed JS/TS projects, the approach included adding a hello.js fixture and comprehensive loader.test.js tests to validate non-TypeScript processing and ensure the new flag’s interoperability with plain JavaScript. Emphasized test-driven development and fixture-driven testing to strengthen coverage and reduce regression risk. Utilized JavaScript and Node.js within a Git-based workflow, prioritizing maintainability and traceability. No major bugs were addressed, as the primary objective centered on feature delivery and robust validation.
