Alternative playground idea

First of all, thank you for creating such a comprehensive resource and making it freely available! As I often get asked about where to start learning JS, this is constantly in my top 3-4 aswers :)

I wonder, are you open to adding an alternative playground option if it would provide an improved experience for your users?

I'm thinking specifically about StackBlitz, some of the benefits being:

• no ads
• familiar editor UI, that a lot of people know from Visual Studio Code
• support for dark/light themes
• a possibility to render a Console right in the UI, which could optionally allow replacing alert with console.log for a non-blocking flow
• a possibility to add Node.js articles in the future, since StackBlitz supports it too (see e.g. https://node.new)

I've made a quick proof of concept of how the experience could look like:

Thanks again, and I'm curious to hear your thoughts!

Empieza por el cuerpo del issue y su prueba de concepto de StackBlitz enlazada. Evalúa si un playground alternativo debería integrarse en el tutorial y define los artículos afectados, la experiencia de usuario y los criterios de aceptación; el issue no identifica archivos, pruebas ni una definición concreta de finalización.
