Worked on the hey-api/openapi-ts repository to enhance developer experience by updating documentation related to asynchronous fetch operations. Focused on clarifying how async functions can be used within fetch client interceptors, the work involved revising fetch.md to demonstrate proper async support and align documentation with actual runtime behavior. This targeted documentation update aimed to reduce onboarding time for new contributors and support future adoption of asynchronous features. The technical approach centered on Markdown for documentation and asynchronous JavaScript concepts, with collaboration across teams to ensure accuracy. No bugs were fixed during this period, and the primary contribution was a documentation feature.
