During March 2026, Jing Qong enhanced TSX readability in the zed-industries/zed repository by refining the rainbow colorization logic for JSX tags. Using Scheme, Jing modified the crates/languages/src/tsx/brackets.scm file to exclude angle brackets from rainbow highlighting, reducing visual noise and aligning TSX behavior with HTML. This front end development work focused on visual design consistency, making code reviews more predictable and improving developer focus across languages. Jing documented the changes in the release notes, ensuring clear communication for future maintainers. The update addressed a nuanced aspect of syntax highlighting, demonstrating careful attention to cross-language user experience and maintainability.
