Worked on the babel/babel repository to address a bug related to async function transformation purity annotations. Focused on refining the transformation logic to prevent async functions using apply() or call() from being incorrectly marked as pure, thereby improving the reliability of Babel’s output for async IIFEs and their bound or called variants. The solution involved targeted AST manipulation and code transformation techniques, ensuring minimal risk and clear code ownership. Utilized JavaScript and TypeScript to implement and test the fix, contributing to more accurate compiler behavior and reducing the likelihood of incorrect optimizations in common async function call patterns.
