Documentation for Danfo.js

description
Danfo.js is an open-source, JavaScript library providing high-performance, intuitive, and easy-to-use data structures for manipulating and processing structured data.

Danfo.js Documentation

Danfo.js is heavily inspired by the Pandas library and provides a similar interface and API. This means users familiar with the Pandas API can easily use Danfo.js.

Main Features

• Danfo.js is fast. It is built on Tensorflow.js, and supports tensors out of the box. This means you can convert danfo data structure to Tensors.
• Easy handling of missing ****data (represented as NaN) in floating point as well as non-floating point data
• Size mutability: columns can be inserted/deleted from DataFrame
• Automatic and explicit alignment: objects can be explicitly aligned to a set of labels, or the user can simply ignore the labels and let Series, DataFrame, etc. automatically align the data for you in computations
• Powerful, flexible groupby functionality to perform split-apply-combine operations on data sets, for both aggregating and transforming data
• Make it easy to convert Arrays, JSONs, List or Objects, Tensors and differently-indexed data structures into DataFrame objects
• Intelligent label-based slicing, fancy indexing, and querying of large data sets
• Intuitive merging and joining data sets
• Robust IO tools for loading data from flat-files (CSV and delimited) and JSON data format.
• Powerful, flexible and intutive API for plotting DataFrames and Series interactively.
• Timeseries-specific functionality: date range generation and date and time properties.
• Robust data preprocessing functions like OneHotEncoders, LabelEncoders, and scalers like StandardScaler and MinMaxScaler are supported on DataFrame and Series
