Contributed SharedArrayBuffer support to napi_create_typedarray in the nodejs/node repository, enabling TypedArray creation directly from SharedArrayBuffer inputs. This work involved extending the Node.js API to support memory sharing and improve addon interoperability for performance-sensitive applications. The implementation required updates in both C and JavaScript, ensuring that the API could handle new input types while maintaining compatibility. Documentation was revised to clearly outline SharedArrayBuffer usage within the API, aligning technical details for developers. The contribution focused on expanding the capabilities of Node.js native addons, emphasizing robust API development and careful integration of new memory management features into existing workflows.
