What people are saying

An invaluable tool for prototyping with JavaScript. As a web developer, using JavaScript all the time, this is a game changer.

Paolo Leopardi

Amazing product that enables analysis and visualization while using JavaScript

Brian Enochson, CTO at The Java Experts

Quick and easy way to get up and running in JavaScript, love the ability to visualize results as you code

Peter Srajer, Senior Data Scientist - Geospatial at Wellsite Masters

The key is that it "just works" right out of the install.

Matthew Abts, CPA

No more switching between TypeScript, R and Python when doing data exploration, now I can keep my data extraction, shaping and visualisation all in TypeScript!

Eugene Duvenage, Technology and Innovation Specialist

Convenient and accessible. Like a REPL on steroids.

Live visualizations as you code

Export to runnable Node.js code and other formats

About the developer

Data-Forge Notebook is bought to you by Ashley Davis, creator of Data-Forge and author of Data Wrangling with JavaScript and Bootstrapping Microservices.

Ashley Davis

I always kickstart my JavaScript coding with Data-Forge Notebook. I can see visual results immediately while I'm coding and it makes it easy to understand what's going on in the code.
