# Overview

> Choose a supported code interpreter language and kernel.

The standard `code-interpreter` template includes Jupyter kernels for:

* Python
* JavaScript
* TypeScript
* R
* Java
* Bash

Pass `language=` when you run an isolated cell, or set the language on a code
context when you want multiple cells to share kernel state.
