Summary
In this chapter, we have successfully covered the data transformation and wrangling functions available in Danfo.js. First, we introduced you to the various wrangling functions for replacing values, filling missing values, and detecting missing values, as well as applying and mapping methods for applying custom functions to your dataset. Knowledge of these functions and techniques ensures you have the required foundation for building data-driven products, as well as getting insights from your data.
Next, we showed you how to use the various merge and concatenation functions in Danfo.js. Finally, we showed you how to calculate descriptive statistics on your dataset.
In the next chapter, we'll take things a step further and show you how to make beautiful and amazing charts/plots using Danfo.js's built-in plotting features, as well as by integrating third-party plotting libraries.
