IJavascript is an `npm` package that provides:
- a Javascript kernel for the [Jupyter](http://jupyter.org/) console and
  notebook, the [Hydrogen](https://atom.io/packages/hydrogen) Atom plugin, the
  [nteract](https://github.com/nteract/nteract) frontend, ...
- and a command, `ijs`, to install the kernel and invoke the Jupyter notebook.

IJavascript shares a significant portion of code with the CoffeeScript kernel,
[jp-coffeescript](https://github.com/n-riesco/jp-coffeescript) and the Babel
kernel, [jp-babel](https://github.com/n-riesco/jp-babel).

This overview is comprised of two sections. A section to describe the purpose of
the main files in this project. Followed by another section to describe the
purpose of the main classes.
