[Req]: JavaScript Playground Tool

### Contact Details

_No response_

### Explain the proposed feature

A tool for writing JavaScript functions and showing the output.

### Explain the possible use cases for the feature

It's sometimes easier to write a function in it's own context, this would provide an easy to access sandbox for testing and developing functions in their own context.

### Any other details you would like to provide?

This tool at minimum should:
- Evaluate and execute JavaScript code from an input field
- Display the output of the code
- Catch and display errors
- Catch infinite loops and display an error

Possible but not required improvements:
- Use the Editor component from the `codemirror-poc` branch of this project
- Have an option for REPL style (run on input change) or run on demand style (with a button) processing
- Show a menu for adding dependencies via unpkg or similar services
