Danfo.js is a JavaScript library providing high-performance, intuitive data structures (Series and DataFrame) for manipulating and processing structured data, heavily inspired by and API-compatible with Python's pandas. It integrates with TensorFlow.js tensors and supports browser and Node.js environments.

Use cases

• manipulate tabular data in javascript like pandas
• clean and transform csv data in nodejs
• convert arrays into dataframes for analysis
• groupby and aggregate datasets in the browser
• convert dataframes to tensorflow.js tensors for machine learning
• merge and join datasets in javascript
• handle missing NaN values in javascript data analysis

When to choose

• you need pandas-like dataframes in JavaScript or TypeScript
• you are building browser-based or Node.js data analysis pipelines
• you want to feed tabular data into TensorFlow.js models
• your team knows pandas and wants a similar API in JS

When to avoid

• you work primarily in Python where pandas is more mature
• you need very large datasets beyond memory where Spark/DuckDB fit better
• you need advanced statistical or plotting features available in pandas ecosystem
