📄️ Getting started with Python
Python is widely used in notebooks. To execute Python code in JupyterLite, a xeus-python kernel is recommended (see JupyterLite kernels for more details).
📄️ Getting started with R
The process to get started with R will be very similar to what is explained on Getting started with Python. The difference will be that you will need xeus-r kernel in your environment and R packages.
