Worked on the typeorm/typeorm repository to enhance the Select Query Builder documentation, focusing on accuracy and clarity for developers. Addressed a documentation bug by correcting a method name from setOnLock to setOnLocked, ensuring consistency with the current API contract. Clarified the behavior of setOnLocked in relation to database row locking, which helps prevent misuse and reduces confusion among users. The work was carried out exclusively in Markdown, leveraging strong documentation skills to improve onboarding and reduce support queries. No new features or code changes were introduced, but the targeted documentation fix contributes to a more reliable developer experience.
