Worked on codebase maintenance for mrdoob/three.js, focusing on improving clarity and maintainability within the front-end JavaScript framework. Addressed technical debt by removing an unused lineWidth property from the Line2NodeMaterial.js file, which helped streamline the API surface and reduce potential misconfigurations for future contributors. This targeted cleanup aligned the behavior of Line2NodeMaterial with the broader Material and NodeMaterial systems, supporting consistency across the codebase. The change was isolated and low-risk, making onboarding easier and reinforcing long-term maintainability. Utilized JavaScript and Three.js expertise to ensure the material system remained clean, clear, and free from unnecessary configuration options.
