arrow-js

Arrow-js is the official JavaScript implementation of Apache Arrow, an open-source standard for high-performance, columnar in-memory data. It is designed for developers building data-intensive applications in Node.js or the browser, enabling zero-copy data sharing and efficient analytics across languages like Python and R. Its interesting because it dramatically reduces serialization overhead and memory usage for large datasets, making it a key tool for modern big data pipelines and WebAssembly integration.
