Worked on the oxc-project/oxc repository to expand linter compatibility for legacy Node.js environments, specifically targeting Node.js 8.x. Addressed syntax limitations by removing the spread operator from the binpath environment assembly and refined the catch command to improve error reporting in older runtimes. These changes, implemented using JavaScript and Node.js development skills, reduced onboarding friction for teams maintaining projects on outdated Node versions. The work focused on linter configuration and usability, ensuring broader adoption across legacy deployments. No bugs were fixed during this period, but the feature delivered increased accessibility for the linter in environments with stricter JavaScript syntax requirements.
