Learn Enough: The Core Idea
The name Learn Enough comes from a simple idea. You do not need to learn every detail of a subject. You only need to learn enough to start building things on your own.
The word dangerous has a positive meaning here. It means you can get work done and solve real problems.
Focus on What Matters First
This approach also means knowing what to skip at the start. Many HTML tutorials teach forms. They explain how to write form code, but the forms do not do anything useful.
Learn Enough HTML to Be Dangerous does not teach forms at all. You need a full programming language to handle form data, so the topic comes later in the series.
Where Forms Fit in the Series
You first learn forms in Learn Enough JavaScript. In that course, you catch and handle form submissions in the browser.
Then you learn forms again in Learn Enough Ruby. That course uses the Sinatra web framework to process form submissions on a back-end server.
