Currently in beta, Beaker lets you work and experiment with data with different languages, but in one environment.
Beaker is a code notebook that allows you to analyze, visualize, and document data using multiple programming languages including Python, R, Groovy, Julia, and Node. Beaker’s plugin-based polyglot architecture enables you to seamlessly switch between languages and add support for new languages.
Sounds like a good place to tuck away your snippets or development in the early stages of larger projects.
