text: Title: TypeScript / JavaScript Support
  Body: ### Description
  
  Hello,
  
  I recently discovered marimo and am impressed with its reactive programming model and improved notebook experience. However, our team heavily relies on TypeScript alongside Python in our development workflow. Currently, we use Jupyter Notebooks with the [tslab TypeScript kernel](https://github.com/yunabe/tslab), which has been essential for our development process.
  
  After reviewing the documentation, I couldn't find any information about support for other programming languages, particularly TypeScript. I understand this might be architecturally challenging given marimo's current design, but I believe TypeScript support would be valuable for several reasons.
  
  I'd appreciate any insights into whether this kind of language support is possible within marimo's architecture, and if so, whether it's being considered for future development.
  
  Would love to hear your thoughts on this potential feature. Happy to provide more details about our use case if helpful.
  
  ### Suggested solution
  
  ### Support JavaScript / Typescript
  
  ## Business Impact & Use Cases:
  1. Supports teams transitioning from Jupyter+tslab who want to leverage marimo's improved features.
  2. Allows for prototyping and testing TypeScript code in the same interactive environment as Python.
  3. Facilitates documentation and knowledge sharing in mixed Python/TypeScript codebases.
  
  ### Alternative

  ### Additional context
  
  Technical Context:
  - Current solution: Jupyter Notebooks + tslab TypeScript kernel
  - Desired: Similar TypeScript execution capabilities within marimo's reactive environment
