IJavascript

IJavascript is an npm package that implements a Javascript kernel for the Jupyter notebook (formerly known as IPython notebook). A Jupyter notebook combines the creation of rich-text documents (including equations, graphs 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/Jupyter messaging protocol. There are kernels available for Python, Julia, Ruby, Haskell and many other languages.

Main Features

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 libzmq3-dev
sudo npm install -g ijavascript

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

Usage

To start an IPython notebook session with the IJavascript kernel, run:

ijs

This command should open the IPython notebook dashboard in your default web browser:
