Overview of this book

Jupyter Notebook is a web-based environment that enables interactive computing in notebook documents. It allows you to create and share documents that contain live code, equations, visualizations, and explanatory text. The Jupyter Notebook system is extensively used in domains such as data cleaning and transformation, numerical simulation, statistical modeling, machine learning, and much more. This book starts with a detailed overview of the Jupyter Notebook system and its installation in different environments. Next we’ll help you will learn to integrate Jupyter system with different programming languages such as R, Python, JavaScript, and Julia and explore the various versions and packages that are compatible with the Notebook system. Moving ahead, you master interactive widgets, namespaces, and working with Jupyter in a multiuser mode. Towards the end, you will use Jupyter with a big data set and will apply all the functionalities learned throughout the book.

Chapter 5.  Jupyter JavaScript Coding

JavaScript is a high-level, dynamic, untyped, and interpreted programming language. There are several, languages that are based on JavaScript. In the case of Jupyter, the underlying JavaScript is really Node.js. Node.js is an event-based framework that uses JavaScript that can be used to develop large, scalable applications. Note, this is in contrast to the earlier languages covered in this book that are primarily used for data analysis (Python is a general language as well, but has clear aspects that deal with its capabilities of performing data analysis).

In this chapter, we will cover the following topics:

  • Adding JavaScript packages to Jupyter

  • JavaScript Hello World Jupyter Notebook

  • Basic JavaScript in Jupyter

  • Node.js d3 package

  • Node.js stats-analysis package

  • Node.js JSON handling

  • Node.js canvas package

  • Node.js plotly package

  • Node.js asynchronous threads

  • Node.js decision-tree package
