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!

Beginne mit dem Issue-Text und dem darin verlinkten StackBlitz-Proof-of-Concept. Bewerte, ob ein alternativer Playground in das Tutorial integriert werden sollte, und lege die betroffenen Artikel, die Benutzererfahrung und die Akzeptanzkriterien fest; das Issue nennt keine Dateien, Tests oder konkrete Definition of Done.
