Learn BEAKERX with Real Code Examples
Updated Nov 26, 2025
Explain
Extends Jupyter notebooks with support for multiple JVM-based languages like Java, Kotlin, Groovy, and Scala, alongside Python.
Provides interactive tables, plots, and forms for rich data visualization.
Enables polyglot notebooks where multiple languages can coexist in a single notebook.
Includes enhanced widgets and tools for data analysis and experimentation.
Encourages teaching, research, and exploratory programming with multi-language support.
Core Features
Multiple language kernels in a single notebook
Interactive plotting and charting
Data table widgets for real-time manipulation
Support for advanced Jupyter magics and cell execution
Notebook sharing via standard Jupyter formats
Basic Concepts Overview
Notebook - interactive document supporting multiple languages
Cell - code block executed in a specific kernel
Kernel - execution engine for a particular language
Widget - interactive GUI element inside a notebook
Output - visual or textual result of cell execution
Project Structure
Sequential cells containing code or markdown
Cells may be in different languages
Outputs include text, tables, plots, or widgets
Notebook files saved locally or in version control
Interactive elements update dynamically in runtime
Building Workflow
Open Jupyter Notebook or Lab with BeakerX enabled
Create notebook and select desired kernel/language
Write code in cells, using widgets or plots as needed
Run cells sequentially or interactively
Save notebook in standard .ipynb format for sharing
Difficulty Use Cases
Beginner: learn Python or JVM language basics
Intermediate: create interactive visualizations or tables
Advanced: develop polyglot notebooks mixing multiple languages
Expert: prototype algorithms or educational demos
Instructor: teach programming and data analysis interactively
