## What it is
IJavascript is a JavaScript kernel for the Jupyter notebook that executes JavaScript code inside a Node.js session. It implements the Jupyter messaging protocol and behaves like the Node.js REPL, with access to npm modules.

## Use cases
- run javascript in jupyter notebooks
- interactive node.js repl in a notebook
- create rich-text documents with executable javascript
- prototype javascript with npm modules in jupyter
- teach javascript in an interactive notebook environment

## When to choose
- you want to run JavaScript/Node.js code inside Jupyter notebooks
- you need an interactive Node.js REPL with rich output
- you're building educational notebooks in JavaScript

## When to avoid
- you need a kernel for another language like Python or Julia
- you need actively developed cutting-edge features
- you don't use Jupyter at all

## Facets
- artifact type: plugin
- maturity: maintenance
- function: interpreter, developer-tools
- domain: developer-tools, data-science, education
- platform: cross-platform
- tags: jupyter-kernel, notebook, repl, javascript, nodejs
