Chapter 4: Data Analysis, Wrangling, and Transformation

Data analysis, wrangling, and transformation are important aspects of any data-driven project, and the majority of your time as a data analyst/scientist will be spent doing one form of data processing or the other. While JavaScript is a flexible language with good features for manipulating data structures, it is quite tedious to write utility functions to perform data wrangling operations all the time. As such, we have built powerful data wrangling and transformation features into Danfo.js, and this can greatly reduce the time that's spent on this stage.

In this chapter, we will show you how to practically use Danfo.js on real-world datasets. You'll learn how to load different types of datasets and analyze them by performing operations such as handling missing values, calculating descriptive statistics, performing mathematical operations, combining datasets, and performing string manipulations.
