In the beginner’s guide to using Observable JavaScript, R, and Python with Quarto, I outlined how to use Observable within a Quarto file. However, one of my top tips for Quarto users learning Observable JavaScript is to write code on the Observable community website. Even if you only plan to use Observable JavaScript in Quarto documents, it’s a good idea to set up a free account and use the tools there. The code snippets alone make having an account worthwhile, and they’ll help you learn the code required for basic tasks.
