How do you know when your HTML and CSS skills are strong enough to begin JavaScript? Is there a checklist or a small project you should be able to build without following a tutorial first? I don't want to delay JavaScript until I'm an expert, but I'd like to make sure my fundamentals are solid enough to understand how everything fits together.

There’s no point at which you become permanently “good enough,” especially since web development keeps changing. Keep improving HTML and CSS while adding JavaScript gradually. Focus on understanding programming basics such as variables, conditionals, loops, functions, and events, then connect those ideas to the DOM through small projects.
Start as soon as you want to build something more interactive than a static page. A simple to-do list is a great first project: add tasks, remove them, and maybe mark them complete. You’ll learn JavaScript logic while also practicing how it changes the page through the DOM.
You don’t really need to finish HTML and CSS before starting JavaScript. They’re separate skills that work together, so learning them alongside each other is usually the most practical approach. Once you understand basic tags, attributes, selectors, and how classes work, you have enough foundation to begin.
You can learn JavaScript with almost no HTML or CSS knowledge, but you’ll need basic HTML concepts when you start manipulating web pages. If you can create a simple, readable page with headings, paragraphs, links, and a little styling, you already know enough to begin experimenting.
