Worked on the prettier/angular-html-parser repository to enhance developer onboarding and API clarity by improving documentation related to signal queries. Focused on reducing ambiguity, the work involved updating the signal-queries.md file and explicitly defining return types for relevant TypeScript methods. This approach aimed to streamline downstream usage and make the codebase more accessible for new contributors, ultimately shortening onboarding time and minimizing support requests. The changes were implemented using Markdown for documentation and TypeScript for code examples, reflecting a commitment to maintainability and clear communication. No bug fixes were recorded during this period, with all efforts directed toward documentation improvements.
