you can try xeus-javascript https://github.com/jupyter-xeus/xeus-javascript, console.log works there.

@martinRenou console.log usually does work in a worker....

how to start the web worker?

@woodgreat according to the screenshot it looks like you are trying to run JavaScript code in a regular JupyterLab with a Python kernel? (since there is the extension manager panel on the left).

I get the same error when trying to execute the same code snippet with ipykernel:

@woodgreat if you want to use the JavaScript kernel, you can for example open https://jupyterlite.github.io/demo/lab/index.html in a browser tab, and make sure you have selected "JavaScript (Web Worker)" as the kernel:

Closing as answered, but don't hesitate to open a new issue if you have more questions!

I assumed it would not work, sorry for the confusion!

The Python traceback formatting should have been another hint 👀
