Worked on improving documentation quality in the nodejs/node repository by addressing a specific issue in the writing-tests guide. Focused on technical writing and documentation skills, the contribution involved correcting a misspelling from "optimial" to "optimal" in the Markdown-based documentation. This targeted bug fix enhanced clarity and professionalism for contributors and users referencing the guide, supporting better onboarding and ongoing maintenance. No functional or code changes were introduced, as the work was limited to documentation updates. The approach emphasized accuracy and traceability, with a clear commit reference provided to ensure transparency and maintainability within the repository’s documentation workflow.
