What is TinyFrameJS?
TinyFrameJS is an open source, MIT-licensed library providing high-performance, easy-to-use data structures and data analysis tools for JavaScript. It implements a lightweight DataFrame concept — a two-dimensional labeled data structure with columns of potentially different types — optimized through column-oriented storage for efficient operations on large datasets. The library supports creating DataFrames from various sources including arrays, objects, CSV, JSON, and Excel files, making it versatile for different data formats.
Built on native JavaScript arrays and objects, TinyFrameJS serves as a fundamental building block for practical, real-world data analysis in JavaScript applications. It maintains excellent performance while providing an intuitive API for filtering, sorting, transforming, and aggregating data. Whether you're building data visualizations, performing financial analysis, or processing user data in web applications, TinyFrameJS offers the tools you need without unnecessary complexity or overhead, making working with structured data fast, easy, and expressive.
