During December 2025, Santiago Garcia contributed to the biomejs/biome repository by implementing a new ESLint rule, no-jsx-props-bind, aimed at improving React component performance and maintainability. Santiago’s work focused on enforcing best practices in JSX prop bindings by disallowing the use of .bind(), arrow functions, or function expressions directly in JSX props, which can lead to unnecessary re-renders. This feature was developed using JavaScript and React, with a strong emphasis on linting standards. The rule was thoroughly documented and collaboratively developed, reflecting a thoughtful approach to code quality and consistency within the codebase, though limited in scope to a single feature.
