jsdataframe
Jsdataframe is a JavaScript data wrangling library inspired by data frame functionality in R and Python Pandas. Vector and data frame constructs are implemented to provide vectorized operations, summarization methods, subset selection/modification, sorting, grouped split-apply-combine operations, database-style joins, reshaping/pivoting, JSON serialization, and more. It is hoped that users of R and Python Pandas will find the concepts in jsdataframe quite familiar.
Jsdataframe works in both Node.js and the browser and has no dependencies.
