IJavascript: A Javascript Kernel for IPython's Graphical Notebook

IJavascript is an npm package that implements a Javascript kernel for IPython's graphical notebook (also known as Jupyter). An IPython notebook combines the creation of rich-text documents (including equations, plots and videos) with the execution of code in a number of programming languages.

The execution of code is carried out by means of a kernel that implements the IPython messaging protocol. There are kernels available for Python, Julia, Ruby, Haskell and many other languages.

Main Features

Run Javascript code within a node.js session
Autocompletion: press TAB to complete keywords and object properties
Object inspection: press Shift-TAB to inspect an object and show its content or, if available, its documentation
Graphical output for HTML, PNG, ...

Installation

The instructions to install IJavascript are platform-dependent. For example, in Ubuntu 14.04, IJavascript and its prerequisites can be installed simply by running:

sudo apt-get install nodejs-legacy npm ipython ipython-notebook libzmq-dev
sudo npm install -g ijavascript

For other platforms, please, refer to the installation notes.
