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.

• Danfo.js is fast and supports Tensorflow.js's tensors out of the box. This means you can convert Danfo.js DataFrames to Tensors, and vice versa.
• Easy handling of missing data (represented as NaN, undefined, or null) in data
• Size mutability: columns can be inserted/deleted from DataFrames
• 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), Excel, and JSON data format.
• Powerful, flexible, and intiutive 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
