Zhurvla

Worked on the mozilla/rhino repository to enhance JavaScript parser compatibility with ES6+ standards, focusing on object literal parsing and numeric fidelity. Updated the parser to allow duplicate properties in ES6+ object literals, aligning Rhino’s behavior with modern JavaScript and adding comprehensive regression tests to validate these scenarios. Implemented IEEE 754-compliant Float16 support in DataView, developing an extensive test suite to cover edge cases such as rounding, denormals, and endianness. Collaborated on both development and testing, using Java and JavaScript to ensure robust parser behavior and numeric accuracy, while maintaining a commit-driven workflow and thorough test coverage throughout.
